CHAPTER 7 8-BIT PWM TIMER

Sleep mode
Wake-up from sleep mode by an interrupt other than IRQ2 (IRQ2 is not generated).
Operation halts
Maintains the level prior to halting.
Operation restarts
Oscillation stabilization delay time
Wake-up from stop mode by an external interrupt.
* : The PWM pin (PWM) goes to the high-impedance state during stop mode if the pin state specification bit in the
standby control register (STBC: SPL) is "1" ("H" level if pull-up is selected for PWM pin).
When the SPL bit is "0", the pin maintains its value prior to entering stop mode.
