UART Module
Functional
UART ADDR_MATCH may not be set in time for the read when running at slow UART speeds.
During an Address match interrupt, when the code jumps into ISR and reads the FIFO. The UART is not able to receive the data which is sent as the address on the RX line, due to the address match interrupt being generated before the STOP bit.
Wait 1 UART CLK cycle before reading the data to allow the ADDR_MATCH to be set.
