Selection of Pin Functions
The function depends on the output enable bit (OE) of PWM timer 3’s timer control
register (TCR), the C/A bit in SCI2’s SMR, the CKE1 and CKE0 bits in SCI2’s SCR,
and the port 9 PWM enable bit (P9PWME) and port 9 serial enable bit (P9SCI2E) in
system control register 2 (SYSCR2).
