2-14 CPU 2.5 Interrupts 2.5.1 Overview of Interrupts The most important key to real-time control is the ability to shift quickly to interrupt handler processing.

2-16 CPU LV2 to LV0 (Interrupt Priority Level) R/W • This 3-bit field sets the interrupt priority level. When the interrupt priority level set in LV2 to LV0 is higher than the interrupt mask level set in IM2 to IM0 in the PSW (i.e., the value set in LV2 to LV0 is smaller than the value set in IM2 to IM0), interrupts in the corresponding interrupt[...]

2-17 CPU [Interrupt Accept Group Register (IAGR)] R halfword/byte access During a register read, the interrupt accept group register (IAGR) indicates the smallest group number of the groups that are generating an interrupt of the interrupt levels accepted by the CPU, which are indicated by IM2 to IM0 of the PSW. This register is allocated to addres[...]

2-18 CPU 2.5.3 Interrupt Types The three types of interrupts are listed below: [Reset interrupt] The reset interrupt is the interrupt with the highest priority level, and is generated by setting the RST pin to "L" level. As a result of the reset interrupt, the registers, etc., are initialized. When the RST pin goes to "H" level,[...]

2-19 CPU [Level interrupts] Level interrupts are interrupts for which the interrupt level can be controlled through the interrupt enable (IE) and interrupt mask (IM2 to IM0) bits in the PSW. Level interrupts are interrupts from the interrupt group controllers external to the CPU (in other words, peripheral interrupts). There are 18 groups, or 35 in[...]

2-20 CPU (Example of pre-processing by the interrupt handler) 1. The registers are saved. The saved registers are those used by the interrupt handler. 2. The interrupt group analysis is executed. 2.1 The interrupt acknowledge sequence is executed. Interrupt acknowledge consists of reading out the interrupt accept group register (IAGR) to obtain the[...]

2-21 CPU An even higher interrupt response speed can be realized by assigning only one factor or only a few factors to a single interrupt level. Fig. 2-5-6 shows the interrupt sequence flow when assigning one factor to each interrupt level. Fig. 2-5-6 Interrupt Sequence Flow [Nested Interrupts] When a level interrupt occurs, nested interrupts can b[...]

2-22 CPU [Stack Frame] When an interrupt is accepted, a stack frame is allocated and the total 6 bytes of information in the PC and PSW are saved in order to return from the interrupt. However, since the transfer of data across the 32-bit boundary is prohibited, the SP value must constantly be set to a multiple of 4. Accordingly, a stack frame is a[...]
