(PARITY CHECKING)
NOTES:
1. Conditions shown are for GEN/CHK = H, OEAB = L, OEBA = H.
2. A-to-B parity checking is shown. B-to-A parity checking is similar but uses OEBA = L, OEAB
3. In parity checking mode the parity bits will be transmitted unchanged along with the

5. Conditions shown are for the byte A0–A7 and PA1. The byte A8–A15 and PA2 is similiar.
6. The parity error flag PERB is a combined flag for both bytes A0–A7 and A8–A15. If a parity
