How it works
If OE == 0 then Y[0:1], YP, Z[0:1] and ZP are in a high-z state.
Output Y[0:1] = (SEL == 0) ? A[0:1] : B[0:1] Output Z[0:1] = (SEL == 0) ? ~A[0:1] : ~B[0:1]
Output YP and ZP are the parity of Y and Z respectively.
POPCNT_Y[0:1] and POPCNT_Z[0:1] are the population count of {Y[0:1],YP} and {Z[0:1],ZP} respectively. These pins are never in high-z state.
