Register
• Interrupt handling—Consists of SIRQ (sheet 4), which is executed after the UART
module generates an interrupt caused by a change-in-break (beginning of a break).
SIRQ then clears the interrupt source, waits for the next change-in-break interrupt
(end of break), clears the interrupt source again, then returns from exception
processing to the system monitor.
Reset the receiver and transmitter.
Reset the mode pointer (MISC[2–0] = 0b001).
Program the vector number for a UART module interrupt.
Enable the preferred interrupt sources.
Initialize the input enable control (IEC bit).
Select the receiver and transmitter clock. Use timer as source if required.
If preferred, program operation of receiver ready-to-send (RxRTS bit).
Select receiver-ready or FIFO-full notification (RxRDY/FFULL bit).
Select character or block error mode (ERR bit).
Select parity mode and type (PM and PT bits).
Select number of bits per character (B/Cx bits).
Select the mode of operation (CMx bits).
If preferred, program operation of transmitter ready-to-send (TxRTS).
If preferred, program operation of clear-to-send (TxCTS bit).
Select stop-bit length (SBx bits).
UART module registers can be accessed by word or byte
operations, but only data byte D[7:0] is valid.
