11.2.1
The port B control register 1 and 2 (PBCR1 and PBCR2) are 16-bit read/write registers that set the
functions of port B pins. Port B consists of the dual use pins TP15–TP0. Bits corresponding to the
pins to be used for TPC output must be set to 1. For details, see the port B description in the
section 15, Pin Function Controller.

and 1 have the same output trigger, the NDRA address is H'5FFFFF5; when their
output triggers are different, the NDRA address for group 0 is H'5FFFFF7 and the
address for group 1 is H'5FFFFF5. Likewise, when TPC output groups 2 and 3 have the
same output trigger, the NDRB address is H'5FFFFF4; when their output triggers are
different, the NDRB address for group 0 is H'5FFFFF6 and the address for group 1 is
H'5FFFFF4.
