Section 17 Subsystem Timer (Subtimer)
17.2.2
SBTDCNT is an 8-bit readable/writable down counter. When SBTDCNT underflows, an interrupt
request is issued and the SBTUF flag in SBTCTL is set to 1. SBTDCNT is initialized to H'FF.
17.2.3
ROPCR is an 8-bit readable/writable register. When the OSCEB bit in SBTCTL is set to 1,
SBTPS counts two system clock cycles from the first falling edge of the on-chip oscillator to the
third falling edge and then transfers the count value to ROPCR. After that, ROPCR configures the
division ratio of subclock. ROPCR is initialized to H'FF.

Description
Subclock Supply Enable
Enables or disables clock supply to the entire chip when
the on-chip oscillator for the subtimer is used.
0: Clock supply is disabled.
1: Clock supply is enabled.
Subtimer Interrupt Request Enable
When this bit is set to 1, an interrupt request caused by
the SBTUF flag is enabled.
Underflow Interrupt Flag
[Setting condition]
When the SBTDCNT value underflows
[Clearing condition]
When 0 is written to this bit after reading 1
