NOTES:

1.These pins also control test mode entry.

2.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 Px_MODE.y = 0, port is as programmed. If Px_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- eral.

12.The values in this column are valid until your software writes to Px_MODE.
