0: disables interrupt propagation to the INT output.

1: enables interrupt propagation to the INT output.

UPDATEE

This bit enables the propagation of interrupt to the INT output when UPDATEV changes state

from 1 to 0. This bit does not have impact on UPDATEI bit

0: disables interrupt propagation to the INT output.

1: enables interrupt propagation to the INT output.

FRAMEE

This bit enables the propagation of interrupt to the INT output when CMP is sampled at the

expected RC1FP position. This bit does not have an impact on FRAMEI bit.

0: disables interrupt propagation to the INT output.

1: enables interrupt propagation to the INT output.

SWAPV

The SWAPV bit contains the current state of the page swap. This bit is logic one when a

switch to the connection memory page (CMP) input has been recognized but the page swap

has not yet happened. This bit is a logic 0 when page swap is not pending.

When a page swap is pending, writing to the offline page or initiating a page copy may cause

corruption of the memory pages.

UPDATEV:

This bit is updated when the active connection memory page is copied to the offline

connection memory page.

0: copying completed.

1: copying in progress.

The duration of a page copy is highly dependent on MF_SWAP.
