10.2.4 Pin Functions
Port 2 pins also function as PPG outputs, TPU I/Os, and interrupt inputs. The correspondence
between the register specification and the pin functions is shown below.
• P27/PO7/TIOCB5/(IRQ15)
The pin function is switched as shown below according to the combination of the TPU channel
5 settings (by bits MD3 to MD0 in TMDR_5, bits IOB3 to IOB0 in TIOR_5, and bits CCLR1
and CCLR0 in TCR_5), bit NDER7 in NDERL, bit P27DDR, and bit ITS15 in ITSR.
