6.3.2.2. Set0.Reg1 - Interrupt Control Register (ICR)
Where UART is used to Legacy UART, and the functions for these bits are defined in the previous
UART, the traditional SIR or ASK-IR based on the legacy UART also has the same definitions. The
advanced UART functions, including Advanced SIR/ASK-IR, MIR, FIR, or Remote IR, are described
as follows.

ETMRI - Enable Timer Interrupt
Write to 1 enable timer interrupt.
EFSFI - Enable Frame Status FIFO Interrupt
Write to 1 enable frame status FIFO interrupt.
Not used.
ETXTHI - Enable Transmitter Threshold Interrupt
Write to 1 enable transmitter threshold interrupt.
EDMAI - Enable DMA Interrupt.
Write to 1 enable DMA interrupt.
EHSRI - Enable HSR (Handshake Status Register) Interrupt
Write to 1 enable handshake status register interrupt. Note that the bit IRHSSL (Infrared
Handshake Select) should be set to 1, then this bit EHSRI is effective.
EUSRI - Enable USR (UART Status Register) Interrupt
Write to 1 enable UART status register interrupt.
EHSRI/ETXURI - Enable USR Interrupt or Enable Transmitter Underrun Interrupt
Write to 1 enable USR interrupt or enable transmitter underrun interrupt.
ETBREI - Enable TBR (Transmitter Buffer Register) Empty Interrupt
Write to 1 enable transmitter buffer register empty interrupt.
ERBRI - Enable RDR (Receiver Buffer Register) Interrupt
Write to 1 enable receiver buffer register interrupt.
