RE: [68300] TPU pin state

2003-01-09 by Melear Charles-rdph40

Hello everyone,
 
Unprogrammed TPU pins become inputs and have no function.
 
They cannot be used as I/O or anything.  Only the TPU can use these pins.

Subject: [68300] TPU pin state


When a TPU pin is not programmed, does it default to an input, output, or 
is it high Z?

What is the proper way to stop a TPU port so that it goes back to default 
state? Just set the channel priority to disabled?

I have a TPU UART transmitter channel that I want to disable until the 
remote party initiates a conversation. I currently set the channel to be a 
receiver until it is needed then it is disabled and turned into a 
transmitter. I have since changed my code to simply set the channel 
priority to disabled until it is needed.
