Section 7 I/O Ports
7.10.3 Pin Functions
The port A pins are also used for TPC output (TP₇ to TP₀), ITU input/output (TIOCB₂ to TIOCB₀,
TIOCA₂ to TIOCA₀) and input (TCLKD, TCLKC, TCLKB, TCLKA), and as address bus pins (A₂₃
to A₂₀). Table 7.16 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
