What is the state of the DAi pin when the DAi output enable bit is "0"?

Latest Updated:03/01/2005

Question:

(D/A Converter)  What is the state of the DAi pin when the DAi output enable bit is "0" (disabled) ? [2005/03/01]

Answer:

When the DAi output enable bit is "0" (disabled), the DAi pin functions as a shared input/output port and its state is determined by the port's direction register.
When the corresponding bit of the port's direction register is "0", this pin is set for input mode, which means it is in high-impedance state. When the corresponding bit of the port's direction register is "1", this pin is set for output mode, which means that it outputs the contents of the port latch. (#104846)
