Mismatch between documentation and Verilog for UART_CTRL[4] - Rx clock source #6

Closed m1geo closed 6 days ago

m1geo commented 6 days ago

The documentation states UART_CTRL[4]=0 uses internal baud rate generator: image

However the Verilog and the 6551 datasheet show the reverse: image

Importantly code remains compatible, but caused me a bit of confusion as I was working from your datasheet :) Thanks!

This is just a doc issue. Docs updated, 0=external, 1 = internal baud generator
