The AUTO_UPDATE bit selects when an off-line page update is performed. When
AUTO_UPDATE is a logic one, the on-line page is automatically copied into the off-line
page whenever there is a change to the connection memory page. When AUTO_UPDATE is
a logic zero, the off-line page is not updated when there is a change to the connection
memory page. A page update may still be performed by writing to the Interrupt Status and
Memory Page Update Register.
A logic one on the SWAP_PENDINGE bit enables the generation of an interrupt on a change
of state of SWAP_PENDINGV.
A logic one on the UPDATEE bit enables the generation of an interrupt on a change of state
from high to low of UPDATEV.
The SWAP_PENDINGV bit contains the current state of the page swap circuitry. This bit is a
logic one when a switch to the connection memory page (CMP) has been recognized but the
page swap has not yet happened. This bit is a logic zero when there is not a page swap
pending.
The UPDATEV bit contains the current state of the time switch ram off-line page update
circuitry. This bit is a logic one when the on-line page is being copied to the offline page.
This bit is a logic zero when the on-line page is not being copied.
