Pin Functions - Renesas H8S/2319 series Hardware Manual

After a reset and in hardware standby mode, PORT2 contents are determined by the pin states, as
P2DDR and P2DR are initialized. PORT2 retains its prior state after in software standby mode.

Pin Functions

Port 2 pins also function as TPU I/O pins (TIOCA3, TIOCB3, TIOCC3, TIOCD3, TIOCA4,
TIOCB4, TIOCA5, and TIOCB5), and 8-bit timer I/O pins (TMRI0, TMCI0, TMO0, TMRI1,
TMCI1, and TMO1). Port 2 pin functions are shown in table 8-5.

Pin Selection Method and Pin Functions
P27/TIOCB5/ The pin function is switched as shown below according to the combination of
TMO1 the TPU channel 5 setting by bits MD3 to MD0 in TMDR5, bits IOB3 to IOB0 in
TIOR5, bits CCLR1 and CCLR0 in TCR5, bits OS3 to OS0 in TCSR1, and bit
P27DDR.
