48.3.15 UART Infrared Register (UARTx_IR)
The IR register controls options for setting the infrared configuration.
Addresses: UART0_IR is 4006_A000h base + Eh offset = 4006_A00Eh
UART1_IR is 4006_B000h base + Eh offset = 4006_B00Eh
UART2_IR is 4006_C000h base + Eh offset = 4006_C00Eh
UART3_IR is 4006_D000h base + Eh offset = 4006_D00Eh
