YI
Multiframe Synchronization Interrupt. When unmasked (MFSYI = 1), an
interrupt is initiated when multiframe synchronization is lost. Interrupt vector =
10000000.
CRC-4 Multiframe Synchronization Interrupt. When unmasked (CSYNI =
1), an interrupt is initiated when CRC-4 multiframe synchronization is lost.
Interrupt vector = 10000000.
Unused.
Remote Signalling Multiframe Alarm Interrupt. When unmasked (YI = 1),
an interrupt is initiated when a remote signalling multiframe alarm signal is
received. Interrupt vector = 10000000.
One Second Status Interrupt. When unmasked (1SECI = 1), an interrupt is
initiated when the 1SEC status bit (page 03H, address 12H, bit 7) changes
from zero to one. Interrupt vector = 00001000.
T1 Timer Interrupt. When unmasked (T1I = 1), an interrupt is initiated when
the T1 timer bit (page 03H, address 12H, bit 5) changes from zero to one.
Interrupt vector = 00001000.
T2 Timer Interrupt. When unmasked (T2I = 1), an interrupt is initiated when
the T2 timer bit (page 03H, address 12H, bit 4) changes from zero to one.
Interrupt vector = 00001000.
Unused
