Selection Method and Pin Functions
P22/PO2/
TIOCC3/
IRQ10
The pin function is switched as shown below according to the combination of the
TPU channel 3 settings (by bits MD3 to MD0 in TMDR3, bits IOC3 to IOC0 in
TIOR3L, and bits CCLR2 to CCLR0 in TCR3), bit NDER2 in NDERL, bit
P22DDR, and bit ITS10 in ITSR.
