Pin Functions

Port 2 pins also function as PPG output pins (PO7 to PO0) and TPU I/O pins (TIOCA3, TIOCB3,

TIOCC3, TIOCD3, TIOCA4, TIOCB4, TIOCA5, and TIOCB5). Port 2 pin functions are shown in

table 9.5.

Table 9.5

Port 2 Pin Functions

Selection Method and Pin Functions

P27/PO7/TIOCB5 The pin function is switched as shown below according to the combination of

the TPU channel 5 setting by bits MD3 to MD0 in TMDR5, bits IOB3 to IOB0 in

TIOR5, bits CCLR1 and CCLR0 in TCR5, bit NDER7 in NDERL, and bit

P27DDR.
