9.7.3 Pin Functions
The port A pins are also used for TPC output (TP₇ to TP₀), ITU input/output
(TIOCB₂ to TIOCB₀, TIOCA₂ to TIOCA₀), ITU input (TCLKD, TCLKC, TCLKB, TCLKA),
DMAC output (TEND₁, TEND₀), and address output (A₂₃ to A₂₀). Table 9-12 describes the
selection of pin functions.

Pin Functions and Selection Method
The mode setting, ITU channel 2 settings (bit PWM2 in TMDR and bits
IOB2 to IOB0 in TIOR2), bit NDER7 in NDERA, and bit PA₇DDR in PADDR
select the pin function as follows
