Functional Modes of Operation There are two primary functional modes of operation for the HPC167064. # EPROM Mode # Normal Running Mode EPROM MODE In the EPROM mode, the HPC167064 is configured to ‘‘ap- proximately emulate’’ a standard NMC27C256 EPROM. Some dissimilarities do exist. The most significant one is that HPC167064 contains only 1[...]

Functional Modes of Operation (Continued) Security Level 2 This security level prevents programming of the on-chip EPROM or the ECON registers thereby providing WRITE protection. Read accesses to the on-chip EPROM or ECON registers may be accomplished without constraint in EPROM. Read accesses to the on-chip EPROM may be accomplished without constr[...]

Pin Descriptions The HPC167064 is available only in 68-pin LDCC package. I/O PORTS Port A is a 16-bit bidirectional I/O port with a data direction register to enable each separate pin to be individually de- fined as an input or output. When accessing external memo- ry, port A is used as the multiplexed address/data bus. Port B is a 16-bit port with[...]

The Port A (see Figure 11 ), consists of a data register and a direction register. Port B (see Figures 12 thru Figure 14 ) has an alternate function register in addition to t[...]

Structure of Port B Pins B10, B11, B12 and B15 (Pins with Bus Control Roles) Operating Modes To offer the user a variety of I/O and expanded memory options, the HPC167064 has four operating modes. The various modes of operation are determined by the state of both the EXM pin and the EA bit in [...]

HPC167064 Operating Modes SINGLE CHIP NORMAL MODE In this mode, the HPC167064 functions as a self-contained microcomputer (see Figure 15 ) with all memory (RAM and EPROM) on-chip. It can address internal memory only, con- sisting of 16 kbytes of EPROM (C000 to FFFF) and 512 bytes of on-chip RAM and Registers (0000 to 02FF). The ‘‘illegal addres[...]

Timer Overview (Continued) (Clock Input/16) rate. It is used for WATCHDOG logic, high speed event capture, and to exit from the IDLE mode. Con- sequently, it cannot be stopped or written to under software control. Timer T0 permits precise measurements by means of the capture registers I2CR, I3CR, and I4CR. A control bit in the register TMMODE confi[...]

Timer Overview (Continued) Maximum output frequency for any timer output can be ob- tained by setting timer/register pair to zero. This then will produce an output frequency equal to (/2 the frequency of the source used for clocking the timer. Timer Registers There are four control registers that program the timers. The divide by (DIVBY) register p[...]

MICROWIRE/PLUS Application Figure 25 illustrates a MICROWIRE/PLUS arrangement for an automotive application. The microcontroller-based sys- tem could be used to interface to an instrument cluster and various parts of the automobile. The diagram shows two HPC167064 microcontrollers interconnected to other MICROWIRE peripherals. HPC167064 1 is set up[...]

HPC167064 UART The HPC167064 contains a software programmable UART. The UART (see Figure 26 ) consists of a transmit shift regis- ter, a receiver shift register and five addressable registers, as follows: a transmit buffer register (TBUF), a receiver buff- er register (RBUF), a UART control and status register (ENU), a UART receive control and stat[...]

Universal Peripheral Interface The Universal Peripheral Interface (UPI) allows the HPC167064 to be used as an intelligent peripheral to anoth- er processor. The UPI could thus be used to tightly link two HPC167064’s and set up systems with very high data ex- change rates. Another area of application could be where a HPC167064 is programmed as an [...]

Design Considerations (Continued) Designs using the HPC family of 16-bit high speed CMOS microcontrollers need to follow some general guidelines on usage and board layout. Floating inputs are a frequently overlooked problem. CMOS inputs have extremely high impedance and, if left open, can float to any voltage. You should thus tie unused inputs to V[...]

HPC167064 CPU The HPC167064 CPU has a 16-bit ALU and six 16-bit regis- ters. Arithmetic Logic Unit (ALU) The ALU is 16 bits wide and can do 16-bit add, subtract and shift or logic AND, OR and exclusive OR in one timing cycle. The ALU can also output the carry bit to a 1-bit C register. Accumulator (A) Register The 16-bit A register is the source an[...]

Code Efficiency One of the most important criteria of a single chip microcon- troller is code efficiency. The more efficient the code, the more features that can be put on a chip. The memory size on a chip is fixed so if code is not efficient, features may have to be sacrificed or the programmer may have to buy a larger, more expensive version of t[...]
