Hi people
I'm upgrading a piece of assembler code from 'C549
to 'C5402. Small problem with the serial port...with the
straightforward serial port control registers for the older device, there is a
bit in the SPC register called IN1, which allows the status of the transmit
bit-clock (BCLKX) to be read. I can't find any equivalent feature in
the newer chip's control registers. Anyone have any
suggestions? It is for a function that introduces a 1 bit delay to
frame-sync routine. I want to avoid having to reconfigure the BCLKX pin as a
general-purpose I/O for one small function like this.
Thank you in advance,
