20.9 Periods in Which CPU Does Not Acknowledge Interrupts
acknowledged between an interrupt request non-sample instruction and the next instruction (interrupt is held pending).
20.10 Caution
related interrupt, and A/D converter-related interrupt, which are alternate functions, do not occur (V850E/IF3: n = 00,
01, 08 to 18, ADT0, ADT1, V850E/IG3: n = 00 to 18, ADT0, ADT1).
1024
The CPU acknowledges an interrupt while an instruction is being executed.
The interrupt request non-sample instructions are as follows.
• EI instruction
• DI instruction
• LDSR reg2, 0x5 instruction (for PSW)
• Store instruction for the command register (PRCMD).
• Store instructions or bit manipulation instructions excluding tst1 instruction for the following registers.
Remark
Note that if a port is set to external interrupt input (INTPn), the timer/counter-related interrupt, serial interface-
• Interrupt-related registers:
• Power save control register (PSC)
Interrupt control register (xxICn) and interrupt mask registers 0 to 5 (IMR0 to IMR5)
