Hi, I was using the ADuC7021 controller. I was planning to use a RS485 driver to interface with an external device.However most of the 485 drivers dont have autodirection features that is it cant transmit or recive automatically. So i was trying to use some logic inside the PLA to program the aurodirection feature. However, I may also use the RS 48f interface to program the controller if necessary. SO I wanted to know if I could use the PLA when the MCU is in boot mode.
