* PQSPAR — QSM Pin Assignment Register
TXD — Transmit Data
This bit determines the direction of the TXD pin (input or output), only if the SCI trans-
mitter is disabled. If the SCI transmitter is enabled, the TXD bit is ignored, and the TXD
pin is forced to function as an output.
PCS[3:1] — Peripheral Chip-Selects 3–1
PCS0/SS — Peripheral Chip-Select 0/Slave Select
SCK — Serial Clock
MOSI — Master Out Slave In
MISO — Master In Slave Out
Refer to
4.4.2 Slave Mode
for additional details on this pin.
All of the above bits determine the QSPI port pin operation to be input or output.
1 = Output
0 = Input
