The incoming data parity (IDP) signal carries the
parity of the incoming signals.
In incoming byte interface mode (IBMODE set
high), the parity calculation encompasses the
ID[7:0] bus and optionally the IC1J1 and the IPL
signals. IC1J1 and IPL can be included in the
parity calculation by setting the INCC1J1 and
INCPL register bits high, respectively. Odd
parity is selected by setting the IOP register bit
high, and even parity is selected by setting the
IOP bit low. IDP is sampled on the rising edge
of SCLK.
In incoming nibble interface mode (IBMODE set
low), The parity calculation encompasses the
ID[3:0] bus and optionally the IC1J1 and the IPL
signals. IC1J1 and IPL can be included in the
parity calculation by setting the INCC1J1 and
INCPL register bits high, respectively. Odd
parity is selected by setting the IOP register bit
high, and even parity is selected by setting the
IOP bit low. IDP is sampled on the rising edge
of NSCLK.
