The UART Address Compare (UxADDR) register stores the multi-node network address
of the UART (see
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.
COMP_ADDR—Compare Address
This 8-bit value is compared to incoming address bytes.
