55 / 84 page ![]() MC68331TS/D 55 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. NOTES: 1. PQS2 is a digital I/O pin unless the SPI is enabled (SPE in SPCR1 set), in which case it becomes SPI serial clock SCK. 2. PQS7 is a digital I/O pin unless the SCI transmitter is enabled (TE in SCCR1 = 1), in which case it be- comes SCI serial output TXD.
