Pin
Selection Method and Pin Functions
P26/PO6/
The pin function is switched as shown below according to the combination of the
TIOCA5/
TPU channel 5 settings (by bits MD3 to MD0 in TMDR5, bits IOA3 to IOA0 in
IRQ14/
TIOR5, and bits CCLR1 and CCLR0 in TCR5), bit NDER6 in NDERL, bit
EDRAK0
EDRAKE in EDMDR0, bit P26DDR, and bit ITS14 in ITSR.
Modes 1, 2, 4, 5, 6, 7 (EXPE = 1)
