This register is used to configure the parity polarity expected on input buses and
generated on output buses.
RODDI, LODDI, BODDI, TODDI:
These bits configure the parity expected on input buses. When high, odd
parity is expected. When low, even parity is expected. The RODDI bit
configures the SINR bus, the LODDI bit configures the SINL bus, the BODDI
bit configures the DINB bus, and the TODDI bit configures the DINT bus.
RODDO, LODDO, BODDO, TODDO:
These bits configure the parity generated on output buses. When high, odd
parity is generated. When low, even parity is generated. The RODDO bit
configures the DOUTR bus, the LODDO bit configures the DOUTL bus, the
BODDO bit configures the SOUTB bus, and the TODDO bit configures the
SOUTT bus. Note that bad parity can be introduced for diagnostic purposes
by manipulating these bits.
