Selectable reference voltage source for an AD converter
(Selectable from VDD, Internal Reference Voltage
Generator Circuit (VREF))
Internal Reference Voltage Generator Circuit (VREF)
Generates 2.0 V/4.0 V for AD converter.
Comparator
Comparator input pin (1 channel)
Comparator output pin (1 channel)
Comparator output set high when (comparator input
level) <1.22 V
Comparator output set low when (comparator input level)
>1.22 V
Clock Output Function
Generates clocks with a clock rate of 1/1, 1/2, 1/4, 1/8,
1/16, 1/32, or 1/64 of the source oscillation clock that is
selected as the system clock.
Watchdog Timer
Generates an internal reset on an overflow occurring in
the timer running on the lowspeed RC oscillator clock
(approx. 30 kHz).
Operating mode at standby is selectable from 3 modes
(continue counting/suspend operation/suspend counting
with the count value retained)
