NOTES:
1. ODD/EVEN and GEN/CHK should be tied to V
CC
or GND with no resistor
for optimum results.
2. The PAx pin input is internally disabled during parity generation. This means
that when generating parity in the A-to-B direction, there is no need to add a
pull-up resistor to guarantee state. The pin will still function properly as the
parity output for the B-to-A direction.
