PORTQS latches I/O data. Writes drive pins defined as outputs. Reads return data present on the pins.
To avoid driving undefined data, first write a byte to PORTQS, then configure DDRQS.
Clearing a bit in the PQSPAR assigns the corresponding pin to general-purpose I/O; setting a bit as-
signs the pin to the QSPI. The PQSPAR does not affect operation of the SCI.

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