Port Integration Module
MC9S12DP256 — Revision 1.1
Port Integration Module
read.
The PWM function takes precedence over the general purpose I/O
function if the associated PWM channel is enabled. While channels 6–0
are output only if the respective channel is enabled, channel 7 can be
PWM output or input if the shutdown feature is enabled.
See Chapter
PWM
.
The SPI function takes precedence over the general purpose I/O
function associated with if enabled.
See Chapter SPI.
If both PWM and SPI are enabled the PWM functionality takes
precedence.
Port P Input
Register (PTIP)
Read: Anytime.
Write: Never; writes to this register have no effect.
This register always reads back the status of the associated pins. This
can be also used to detect overload or short circuit conditions on output
pins.
