Register Description
The SPI Receive Count register designates the block byte length
for the SPI receive DMA transfer.
Count (Bits [10:0])
The Count field sets the count for the SPI receive DMA transfer.
Reserved
Write all reserved bits with ’0’.
UART Registers
There are three registers dedicated to UART operation. Each of
these registers is covered in this section and summarized in
Table 119.
UART Control Register [0xC0E0] [R/W]
Register Description
The UART Control register enables or disables the UART,
allowing GPIO28 (UART_TXD) and GPIO27 (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 divide the baud rate
by eight.
1: Enable prescaler
0: Disable prescaler
Baud Select (Bits [3:1])
Refer to Table 121 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 GPIO28 and GPIO27 to be used
for general use.
Reserved
Write all reserved bits with ’0’.
