If Disable Reset Out = 0, pin is LoZ0. Else if Disable Reset Out =1, pin is HiZ.
3.
If EA# = 0, Port 3 and Port 4 = HiZ. If EA# = 1, Port 3 and Port 4 = ODIO.
4.
If EA# = 1, pin is WK1. If EA# = 0, P5.0, P5.3, and P5.5 are configured as outputs and function as
ADV#, RD#, or BHE# respectively.
5.
If XTAL1 = 1, pin is LoZ0. If XTAL1 = 0, pin is LoZ1.
6.
If P5_MODE.0 = 0, port is as programmed.
If P5_MODE.0 = 1 and CCR.3 = 1 (ALE mode), pin is LoZ0. If P5_MODE.0 = 1 and CCR.3 = 0 (ADV#
mode), pin is LoZ1.
7.
If P5_MODE.1 = 0, port is as programmed. If P5_MODE.1 = 1, pin is LoZ0.
8.
If P5_MODE. y = 0, port is as programmed. If P5_MODE. y = 1, pin is LoZ1.
9.
If P5_MODE. y = 0, port is as programmed. If P5_MODE. y = 1, pin is HiZ.
10. If P x _MODE. y = 0, port is as programmed. If P x _MODE. y = 1, pin is as specified by the associated
peripheral.
11. If output port, pin is as programmed. If special function, pin is as specified by the associated periph-
