The QSMCM uses 11 pins. These pins, when not being used by the serial sub-systems, form a parallel port
on the MCU.
The port QS pin assignment register (PQSPAR) governs the usage of QSPI pins. Clearing a bit assigns the
corresponding pin to general-purpose I/O; setting a bit assigns the pin to the QSPI.
PQSPAR does not affect operation of the SCI. When the SCIx transmitter is disabled, TXDx is a discrete
output; when the SCIx receiver is disabled, RXDx is a discrete input. When the SCIx transmitter or
receiver is enabled, the associated TXDx or RXDx pin is assigned its SCI function.
The port QS data direction register (DDRQS) determines whether QSPI pins are inputs or outputs.
Clearing a bit makes the corresponding pin an input; setting a bit makes the pin an output. DDRQS affects
both QSPI function and I/O function.
function.
DDRQS does not affect SCI pin function. TXDx pins are always outputs, and RXDx pins are always
inputs, regardless of whether they are functioning as SCI pins or as PORTQS pins.
