MC68332 MOTOROLA
MC68332TS/D 69
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 becomes SCI serial output TXD.
DDRQS determines whether 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.
