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.
COMP_ADDR—Compare Address
This 8-bit value is compared to the incoming address bytes.
The UART Baud Rate High and Low Byte registers (see
page 117) combine to create a 16-bit baud rate divisor value (BRG[15:0]) that sets the data
transmission rate (baud rate) of the UART. To configure the Baud Rate Generator as a
timer with interrupt on time-out, complete the following procedure:
1. Disable the UART by clearing the REN and TEN bits in the UART Control 0 register
2. Load the desired 16-bit count value into the UART Baud Rate High and Low Byte
3. Enable the Baud Rate Generator timer function and associated interrupt by setting the
When configured as a general purpose timer, the UART BRG interrupt interval is calcu-
