#139084 - I'm not corious Responding to: ???'s previous message |
but reading a port latch is a curiousity, the potential implications (what if one pin is a clock) and the number of cycles is a menace.
After verifying the need, I shadowed the port, but that took umpteen places of change, just needed the proof, thus the port latch read. Erik |
