Address: 0x00cb_0005
Read: Anytime; normally read only after SPIF is set
Write: Anytime; see WCOL
SPIDR is both the input and output register for SPI data. Writing to
SPIDR while a transmission is in progress sets the WCOL flag and
disables the attempted write. Read SPIDR after the SPIF flag is set and
before the end of the next transmission. If the SPIF flag is not serviced
before a new byte enters the shift register, the new byte and any
successive bytes are lost. The byte already in the SPIDR remains there
until SPIF is serviced.
