The subtimer is a timer for controlling subsystem which has an on-chip oscillator for supplying
system clocks in subactive and subsleep modes and an on-chip 8-bit down counter. Since the
subtimer has a prescaler that can set the division ratio by software, it can supply a clock with any
frequency. This LSI has an on-chip single-channel subtimer.
17.1
On-chip oscillator
Oscillation frequency: 64 kHz to 850 kHz
Temperature characteristic: Source clock 10
Counter: two
8-bit readable/writable down counter
8-bit counter for measuring oscillation frequency of the on-chip oscillator
CPU interrupt source
Underflow (interrupt interval: 731 sec to 67.4 msec)
Subtimer clock supply operating modes:
Subactive mode
Subsleep mode
On-chip oscillator
The on-chip oscillator supplies three kinds of clocks:
Subactive or subsleep mode (
Subtimer down counter (input clock)
Watchdog timer (input clock)
Subtimer prescaler (SBTPS)
The subtimer prescaler is a divider which controls input clocks to the counter which measures
oscillation cycle of the on-chip oscillator and the down counter for the subtimer.
