Description
Reserved.
Transmission complete interrupt is disabled.
Transmission complete interrupt is generated when both the transmit hold
register and the transmit shift register are empty.
Modem interrupt on edge detect of status inputs is disabled.
Modem interrupt on edge detect of status inputs is enabled.
Line status interrupt is disabled.
Line status interrupt is enabled for receive data errors: incorrect parity bit
received, framing error, overrun error, or break detection.
Transmit interrupt is disabled.
Transmit interrupt is enabled. Interrupt is generated when the transmit
FIFO/buffer is empty indicating no more bytes available for transmission.
Receive interrupt is disabled.
Receive interrupt and receiver time-out interrupt are enabled. Interrupt is
generated if the FIFO/buffer contains data ready to be read or if the
receiver times out.
