7.2.4
P1PCR controls the on or off state of input pull-up MOSs for port 1.
7.2.5
When the PWnS bit in PTCNT0 is cleared to 0, port 1 pins can be used as PWM output pins (PW7
to PW0). The pin function relationships are listed below.
According to the combinations of operating modes and the OEn bit, PWnS bit, and P1nDDR bit in
PWOER of the PWM, pin functions change as follows.

Description
•
•
In normal extended and single-chip modes
When the pins are in the input states, the
corresponding input pull-up MOS is turned on
when a P1PCR bit is set to 1.
In multiplex extended mode
When using 16-bit bus width, operation is not
affected.
When using 8-bit bus width, operates as single-
chip mode.
