Section 9 8-Bit PWM Timers
9.2.5
PCSR is an 8-bit readable/writable register that selects the PWM timer input clock.
PCSR is initialized to H'00 by a reset, and in hardware standby mode.
Bits 7 to 3—Reserved: These bits cannot be modified and are always read as 0.
Bits 2 and 1—PWM Clock Select (PWCKB, PWCKA): Together with bits PWCKE and
PWCKS in PWSL, these bits select the internal clock input to TCNT in the PWM timer. For
details, see section 9.2.1, PWM Register Select (PWSL).
Bit 0—Reserved: Do not set this bit to 1.
9.2.6
P1DDR is an 8-bit write-only register that specifies the input/output direction and PWM output for
each pin of port 1 on a bit-by-bit basis.
Port 1 pins are multiplexed with pins PW0 to PW7. The bit corresponding to a pin to be used for
PWM output should be set to 1.
For details on P1DDR, see section 8.2, Port 1.
