NOTE:
1. The expression for CSADOUT2 must include the following write operation cycle signals:
For CRRWR = 0, CSADOUT2 must include WR = 0.
For CRRWR = 1, CSADOUT2 must include E = 1 and R/W = 0.

10.2.2 Port A (PA0-PA7) in Non-Multiplexed Address/Data Mode
In this mode, Port A becomes the low-order data bus byte of the chip. When reading an
internal location, data is presented on Port A pins to the MCU. When writing to an internal
location, data present on Port A pins from the MCU is written to the desired location.
