CSRB - Clock select register channel B (address 0x9) bit description
Description
Receiver clock select. The baud rate clock for the channel B receiver is as
shown in
The receiver clock is always a 16 clock except for CSRB[7:4] = 1111
Transmitter clock select. The baud rate clock for the channel A transmitter is
as shown in
The transmitter clock is always a 16 clock except for CSRB[3:0] = 1111
