What is the state of DAi pins when the DAi Output Enable Bits are "0"?

Latest Updated:02/27/2012

Question:

What is the state of the DAi pins when the DAi Output Enable Bits are "0"(output disable) ?

Answer:

The state depends on the Port Direction Register as the DAi pins are shared with the I/O Port and the DAi pins are I/O Port Function when the DAi output enable bits are "0"(output disable).
The DAi pin switches into high-impedance state since the DAi pin is input when the relevant bit of the direction register is "0".
The DAi pin outputs the content of the port latch since the DAi pin is output when the relevant bit of the direction register is "1".
