We are not seeing a write to UART FCR register bit 5. How do you recommend writing to this bit. Is the sequence:
LCR = 0x80
FCR = 1
FCR = 0x21
Correct to get the bit 5 set?
We are also writing to bits 6 and 7 of FCR. These do not require LCR to be set, correct?
Here we are doing
FCR = 0xF1
1 msec delay
FCR = 0xF7
I don’t think the above top sequence is correct. We are reading register #2 (IIR) and it is giving a 0x12??
