Description
Reserved
The modem interrupt on edge detect of status inputs is
disabled.
The modem interrupt on edge detect of status inputs is
enabled.
The line status interrupt is disabled.
The line status interrupt is enabled for receive data errors:
incorrect parity bit received, framing error, overrun error, or
break detection.
The transmit interrupt is disabled.
The transmit interrupt is enabled. An interrupt is generated
when the transmit FIFO buffer is empty indicating no bytes are
available for transmission.
The receive interrupt is disabled.
The receive interrupt and receiver time-out interrupt are
enabled. An interrupt is generated if the FIFO buffer contains
data ready for a READ or if the receiver times out.
