Chapter 23 DQ256 Port Integration Module (S12XDQ256PIMV2)
23.0.5.23 Port S Data Register (PTS)
Read: Anytime.
Write: Anytime.
Port S pins 7–4 are associated with the SPI0. The SPI0 pin configuration is determined by several status
bits in the SPI0 module. Refer to SPI section for details. When not used with the SPI0, these pins can be
used as general purpose I/O.
Port S bits 3–0 are associated with the SCI1 and SCI0. The SCI ports associated with transmit pins 3 and
1 are configured as outputs if the transmitter is enabled. The SCI ports associated with receive pins 2 and
0 are configured as inputs if the receiver is enabled. Refer to SCI section for details. When not used with
the SCI, these pins can be used as general purpose I/O.
If the data direction bits of the associated I/O pins are set to logic level “1”, a read returns the value of the
port register, otherwise the buffered pin input state is read.
