NOTES:
1. If P5_MODE.
y
= 0, port is as programmed.
If P5_MODE.
y
= 1 and HLDA# = 1, P5.0 and P5.1 are LoZ0; P5.5 is LoZ1.
If P5_MODE.
y
= 1 and HLDA# = 0, port is HiZ.
2. If P5_MODE.
y
= 0, port is as programmed. If P5_MODE.y = 1, port is HiZ.
3. If P
x
_MODE.
y
= 0, port is as programmed.
If P
x
_MODE.
y
= 1, pin is as specified by P
x
_DIR and the associated peripheral.
4. If P2_MODE.7 = 0, pin is as programmed. If P2_MODE.7 = 1, pin is LoZ0.
5. If XTAL1 = 0, pin is LoZ1. If XTAL1 = 1, pin is LoZ0.
6. If EA# = 0, port is HiZ. If EA# = 1, port is open-drain I/O (ODIO).
7. Pins configured as address are high-impedance; pins configured as I/O remain unchanged.
