M16C/6N Group (M16C/6NK, M16C/6NM) Table 8.5 Interrupts to Exit Wait Mode and Use Conditions Interrupt CM02 Bit = 0 _______ NMI Interrupt Can be used Serial Interface Interrupt Can be used when operating with internal or external clock Key Input Interrupt Can be used A/D Conversion Interrupt Can be used in one-shot mode or single sweep mode Timer A Interrupt Can be used in all modes Timer B interrupt ______ INT Interrupt Can be used CAN0/1 Wake-up Interrupt Can be used in CAN sleep mode 8. Clock Generating Circuit CM02 Bit = 1 Can be used Can be used when operating with external clock Can be used - (Do not use) Can be used in event counter mode or when the count source is fc32 Can be used Can be used in CAN sleep mode If the microcomputer is to be moved out of wait mode by a peripheral function interrupt, set up the following before executing the WAIT instruction. (1) Set the ILVL2 to ILVL0 bits in the interrupt control register, for peripheral function interrupts used to exit wait mode. The ILVL2 to ILVL0 bits in all other interrupt control registers, for peripheral function interrupts not used to exit wait mode, are set to “000b” (interrupt disable). (2) Set the I flag to “1”. (3) Start operating the peripheral functions used to exit wait mode. When the peripheral function interrupt is used, an interrupt routine is performed as soon as an interrupt request is acknowledged and the CPU clock is supplied again. When the microcomputer exits wait mode by the peripheral function interrupt, the CPU clock is the same clock as the CPU clock executing the WAIT instruction.
