Write:
Bit 5 of the port D data register (PD5) is dedicated as the slave select
(SS) input. In SPI slave mode, DDD5 has no meaning or effect. In SPI
master mode, DDD5 affects PD5 as follows:
When the SPI is enabled, SPI input pins remain functioning
regardless of the state of the corresponding DDD[4:2] bits. For SPI
output pins, however, the corresponding DDD[4:2] bits must be set or
the pins will function as general-purpose inputs.

0 = PD5 is an error-detect input to the SPI.
1 = PD5 is configured as a general-purpose output line.
