INT

INTC1, INTC0:

The INTC1 and INTC0 bits control when an interrupt is asserted based on the

number of received data bytes in the FIFO as follows:

INTC1

INTC0

Description

Disable interrupts (All sources)

Enable interrupt when FIFO receives

data

Enable interrupt when FIFO has 2

bytes of data

Enable interrupt when FIFO has 3

bytes of data

INT:

The INT bit reflects the status of the external RDLINT interrupt unless the

INTC1 and INTC0 bits are set to disable interrupts. In that case, the RDLINT

output is forced to 0 and the INT bit of the Interrupt Control/Status register will

reflect the state of the internal interrupt latch.

FIFO:

In addition to the FIFO fill status, interrupts are also generated for EOM (end

of message), OVR (FIFO overrun), detection of the abort sequence while not
