5.24.2.5 UART_IER_CIR Register

24.2.5.1 UART_IER_CIR Register (Offset = 4h) [reset = 0h]

The interrupt enable register (IER) can be programmed to enable/disable any interrupt. There are 6 types of interrupt in these modes, TX status, status FIFO interrupt, RX overrun, last byte in RX FIFO, THR interrupt and RHR interrupt and they can be enabled/disabled individually.
