DDRQS determines the direction of the TXD pin only when the SCI transmitter is dis-
abled. When the SCI transmitter is enabled, the TXD pin is an output.
SPCR0 contains parameters for configuring the QSPI and enabling various modes of
operation. The CPU has read/write access to SPCR0, but the QSM has read access
only. SPCR0 must be initialized before QSPI operation begins. Writing a new value to
SPCR0 while the QSPI is enabled disrupts operation.
0 = QSPI is a slave device.
1 = QSPI is system master.
