UART Address Compare Register
The UART Address Compare Register stores the multinode network address of the UART.
When the MPMD[1] bit of UART Control Register 0 is set, all incoming address bytes are
compared to the value stored in the Address Compare Register. Receive interrupts and
RDA assertions only occur in the event of a match.

Description

Compare Address
COMP_ADDR This 8-bit value is compared to incoming address bytes.
UART Baud Rate High and Low Byte Registers
The UART Baud Rate High and Low Byte registers (Table 71 and Table 72) combine to
create a 16-bit baud rate divisor value (BRG[15:0]) that sets the data transmission rate
(baud rate) of the UART.
