RESET:
Clearing a bit in PQSPAR assigns the corresponding pin to general-purpose I/O; set-
ting a bit assigns the pin to the QSPI. PQSPAR does not affect operation of the SCI.
Table D-32 displays PQSPAR pin assignments.
DDRQS determines whether pins configured for general purpose I/O 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. Table D-33 shows
the effect of DDRQS on QSM pin function.

1. PQS2 is a digital I/O pin unless the SPI is enabled (SPE in SPCR1
2. PQS7 is a digital I/O pin unless the SCI transmitter is enabled (TE in
PQSPAR Field
set), in which case it becomes the QSPI serial clock SCK.
SCCR1 = 1), in which case it becomes the SCI serial output TXD.
