Prescaler register 1 (PSCR1) is an 8-bit register. The ATU has one PSCR1 register.
PSCR1 is an 8-bit readable/writable register that enables the first-stage counter clock ' input to
each free-running counter (TCNT0 to TCNT9) and down-counter (DCNT10A to DCNT10H) to be
set to any value from /1 to /32.
Input counter clock ' is determined by setting PSCA to PSCE: ' is /1 when the set value is
H'00, and /32 when H'1F.
PSCR1 is initialized to H'00 by a power-on reset, and in hardware standby mode and software
standby mode.
The internal clock ' set with this register can undergo further second-stage scaling to create clock
