5.2.10 Port 11
Port 11 is an 8-bit I/O port for which I/O settings can be controlled in 1-bit units.
P11 can be read/written in 8- or 1-bit units.
Turning on and off the wait function and setting use as the CANTX1, CANRX1, CANTX2, and CANRX2 pins can
be performed via the port alternate-function control register (PAC) (CANTX2 and CANRX2 are available only for the
µ
PD703089Y and 70F3089Y).

Remark
In input mode:
When P11 is read, the pin levels at that time are read. Writing to P11 writes the
values to that port. This does not affect the input pins.
In output mode: When P11 is read, the values of P11 are read. Writing to P11 writes the values to
that port, and those values are immediately output.
Port 11 includes the following alternate functions.
