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.
Sa6 Value Bits 3-0 Mask. This is the mask bit for the Sa6V*I 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.
not used.
Eight Consecutive Sa6 Nibbles Mask. This is the mask bit for the Sa6N8I 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.
Sa6 Nibble Change Mask. This is the mask bit for the Sa6NI 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.
Sa Nibble Change Mask. This is the mask bit for the SaNI 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.
Sa5 Bit Change Mask. This is the mask bit for the Sa5TI 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.
Sa Bit Change Mask. This is the mask bit for the SaTI 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.
Receive Channel Associated Signaling (CAS) Mask. This is the mask bit for the CASRI
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.
CRC-4 Alignment 2ms Timer Mask. This is the mask bit for the CALNI 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.
