DDRQS7 determines the direction of PQS7 only when the SCI transmitter is disabled.
When the SCI transmitter is enabled, PQS7 is the TXD output.
SPCR0 contains parameters for configuring the QSPI and enabling various modes of
operation. SPCR0 must be initialized before QSPI operation begins. Writing a new val-
ue to SPCR0 while the QSPI is enabled disrupts operation.
0 = QSPI is a slave device.
1 = QSPI is the system master.
0 = Pins designated for output by DDRQS operate in normal mode.
1 = Pins designated for output by DDRQS operate in open-drain mode.
