DS3/E3 Frame Synchronizer Block Interrupt Enable:
This READ/WRITE bit-field permits the user to enable or disable
the Frame Synchronizer block for Interrupt Generation. If the
user enables the Frame Synchronizer block (for Interrupt Gener-
ation) at the block level, the user still needs to enable the inter-
rupts at the "Source" level, as well; in order for these interrupts to
be enabled.
However, if the user disables the Frame Synchronizer block (for
Interrupt Generation) at the Block Level, then ALL Frame Syn-
chronizer-related blocks are disabled.
0 - Frame Synchronizer block is Disabled for Interrupt Genera-
tion.
1 - Frame Synchronizer block is enabled (at the Block level) for
Interrupt Generation.

enables the Frame Generator block (for Interrupt Generation) at
the block level, the user still needs to enable the interrupts at the
"Source" level, as well; in order for these interrupts to be

One Second Interrupt
R/W
One Second Interrupt Enable:
This READ/WRITE bit-field permits the user to enable or disable
the One-Second Interrupt. If the user enables this interrupt, then
the XRT79L71 will generate an interrupt at one second intervals.
0 - One Second Interrupt is disabled.
1 - One Second Interrupt is enabled.
