PRBSOM
PRBS
Interrupt
. When unmasked
(PRBSO = 1), an interrupt is
initiated on overflow of PRBS
counter (page 04H, address
10H) from FFH to 0H. If 1 -
unmasked, 0 - masked.

JAIM
Jitter Attenuation Interrupt Mask.
When unmasked, an interrupt will be
initiated when the jitter attenuator
FIFO comes within four bytes of an
overflow or underflow condition. If 1 -
unmasked, 0 - masked.

1SECIM
One Second Status Interrupt Mask
.
When unmasked (1SECI = 1), an
interrupt is initiated when the 1SEC
status bit changes from zero to one. If
1 - unmasked, 0 - masked.
2
5SECIM
Five Second Status Interrupt Mask.
When unmasked (5SECI = 1), an
interrupt is initiated when the 5SECI
status bit changes from zero to one. If
1 - unmasked, 0 - masked.

RCRIM
RCRI
Interrupt
Mask.
When
unmasked (RCRI=1), an interrupt is
initiated when RCR (remote alarm &
CRC-4 error) status bit changes from
zero to one. If 1 - unmasked, 0 -
masked.
