If P5_MODE. x = 0, port is as programmed.

If P5_MODE. x = 1 and HLDA# = 1, P5.0 and P5.1 are LoZ0; P5.5 is LoZ1.

If P5_MODE. x = 1 and HLDA# = 0, port is HiZ.

If P5_MODE. x = 0, port is as programmed. If P5_MODE. x = 1, port is HiZ.

If P x _MODE. x = 0, port is as programmed.

If P x _MODE. x = 1, pin is as specified by P x _DIR and the associated peripheral.

If P2_MODE.7 = 0, pin is as programmed. If P2_MODE.7 = 1, pin is LoZ0.

If XTAL1 = 0, pin is LoZ1. If XTAL1 = 1, pin is LoZ0.

If EA# = 0, port is HiZ. If EA# = 1, port is open-drain I/O.

On the 8XC196KS and KT, CLKOUT is HiZ during RESET# active.

Although these signals are weakly pulled high or low, do not allow them to float. Always tie these sig-

nals to their inactive state (V

The values in this column are valid until user code configures the specific signal (i.e., until P x _MODE

is written).
