0x0000_0000
UART Interrupt Identification and Interrupt Clear Register. Interrupt status is
read from UART2IntIDIntClr. A write to UART2IntIDIntClr clears the modem
status interrupt. All the bits are cleared to 0 when reset.

0x0000_0000
UART IrDA Low Power Divisor Register. This is an 8-bit read/write register
that stores the low-power counter divisor value used to generate the
IrLPBaud16 signal by dividing down of UARTCLK. All the bits are cleared to 0
when reset.
