UART Control Register [0xC0E0] [R/W]
Register Description
The UART Control register enables or disables the UART
allowing GPIO7 (UART_TXD) and GPIO6 (UART_RXD) to be
freed up for general use. This register must also be written to
set the baud rate, which is based on a 48-MHz clock.
Scale Select (Bit 4)
The Scale Select bit acts as a prescaler that will divide the
baud rate by eight.
1: Enable prescaler
0: Disable prescaler
UART Status Register [0xC0E2] [R]
Register Description
The UART Status register is a read-only register that indicates the status of the UART buffer.

Refer to
Table 37.UART Baud Select Definition
UART Enable (Bit 0)
The UART Enable bit enables or disables the UART.
1: Enable UART
0: Disable UART. This allows GPIO6 and GPIO7 to be used
for general use
Reserved
All reserved bits must be written as ‘0’.
