14 Sa5VM Sa5 Value Bit Mask. This is the mask bit for the Sa5VI interrupt status bit in the National
(CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If this
mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero, the
corresponding interrupt bit will function normally.
13 Sa6V3M Sa6 Value Bits 3-0 Mask. This is the mask bit for the Sa6V*I interrupt status bit in the
13 Sa6V2M National (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If
12 Sa6V1M this mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero,
11 Sa6V0M the corresponding interrupt bit will function normally.

9 Sa6N8M Eight Consecutive Sa6 Nibbles Mask. This is the mask bit for the Sa6N8I interrupt status bit
(0) in the National (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address
Y36). If this mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit
is zero, the corresponding interrupt bit will function normally.
8 Sa6NM Sa6 Nibble Change Mask. This is the mask bit for the Sa6NI interrupt status bit in the
(0) National (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If
this mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero,
the corresponding interrupt bit will function normally.
7 SaNM Sa Nibble Change Mask. This is the mask bit for the SaNI interrupt status bit in the National
(0) (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If this
mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero, the
corresponding interrupt bit will function normally.
6 Sa5TM Sa5 Bit Change Mask. This is the mask bit for the Sa5TI interrupt status bit in the National
(0) (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If this
mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero, the
corresponding interrupt bit will function normally.

SaTM Sa Bit Change Mask. This is the mask bit for the SaTI interrupt status bit in the National
(0) (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address Y36). If this
mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit is zero, the
corresponding interrupt bit will function normally.
4 CASRM Receive Channel Associated Signaling (CAS) Mask. This is the mask bit for the CASRI
(0) interrupt status bit in the National (CAS, National, CRC-4 Local and Timers) Interrupt Status
Register (address Y36). If this mask bit is one, the corresponding interrupt bit will remain
inactive. If this mask bit is zero, the corresponding interrupt bit will function normally.
3 CALNM CRC-4 Alignment 2ms Timer Mask. This is the mask bit for the CALNI interrupt status bit in
(0) the National (CAS, National, CRC-4 Local and Timers) Interrupt Status Register (address
Y36). If this mask bit is one, the corresponding interrupt bit will remain inactive. If this mask bit
is zero, the corresponding interrupt bit will function normally.
