const int CTSPin = 13; // GPIO13 for CTS input
pinMode(CTSPin, FUNCTION_4); // make pin U0CTS
U0C0 |= UCTXHFE; //add this sentense to add a tx flow control via MTCK( CTS )
Isn't the correct program line:
U0C0 |= 2^UCTXHFE; //add this sentense to add a tx flow control via MTCK( CTS )
Since the bit needs to be set? UCTXHFE is 15 which is the correct bit in the register. Otherwise bits 0, 1, 2, 3 are set, I believe. Where am I going wrong?
Thanks,
