UART Address Compare Register
The UART Address Compare (UxADDR) register stores the multi-node network address
of the UART (see
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 reg-
ister. Receive interrupts and RDA assertions only occur in the event of a match.

This 8-bit value is compared to incoming address bytes.
UART Baud Rate High and Low Byte Registers
The UART Baud Rate High (UxBRH) and Low Byte (UxBRL) registers (Tables
combine to create a 16-bit baud rate divisor value (BRG[15:0]) that sets the data trans-
mission rate (baud rate) of the UART.
