8.11
There are three registers dedicated to UART operation. Each of these registers is covered in this section and summarized in
Figure 8-77
.
UART Registers
8.11.1
UART Control Register [0xC0E0] [R/W]
Figure 8-78. UART Control Register
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
Baud Select
(Bits [3:1])
Refer to
Table 8-11
for a definition of this field.
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
