The port QS data register (PORTQS) latches I/O data. PORTQS writes drive pins defined as outputs.
PORTQS reads return data present on the pins. To avoid driving undefined data, write the first data to
PORTQS before configuring DDRQS.
15.5.1
PORTQS determines the actual input or output value of a QSMCM port pin if the pin is defined as
general-purpose input or output. All QSMCM pins can be used as general-purpose input and/or output.
When the SCIx transmitter is disabled, TXDx is a discrete output; when the SCIx receiver is disabled,
RXDx is a discrete input. Writes to this register affect the pins defined as outputs; reads of this register
return the actual value of the pins.

QSMCM Pin
The PORTQS register can be written either as a half-word (16-bit) or as 2
individual bytes (8-bit). This allows the SCI GPIO pin data to written
separately than the QSPI GPIO pin values. This allows either the SCI pins
or the QSPI pins to be used independently as GPIO.
PCS0/SS
SCK/QGPIO6 is a digital I/O pin unless the SPI is enabled (SPE set in SPCR1), in which case
it becomes the QSPI serial clock SCK.
