Software Interrupt Indication: A 1 indicates that a latched alarm has
occurred for which the corresponding interrupt mask bit(s) is/are set to 1.
External Clock Interrupt Indication: Enabled when a 1 is written into
the ECKMSK bit. A 1 indicates that the external clock at input lead
EXTCK has failed (i.e., LEXTC=1).
A Side Interrupt Indication: Enabled when a 1 is written into the
ASMSK bit. A 1 indicates that an alarm has occurred in one of the A-side
alarm registers (i.e., 022H and 024H, bits 2, 1 and 0).
B Side Interrupt Indication: Enabled when a 1 is written into the
BSMSK bit. A 1 indicates that an alarm has occurred in one of the B-side
alarm registers (i.e., 026H and 028H, bits 2, 1 and 0).
Port 4 Interrupt Indication: Enabled when a 1 is written into the P4MSK
bit. A 1 indicates that an alarm has occurred in one of the port 4 alarm
registers for which the corresponding additional interrupt mask bit is also
set to 1 (addresses 017H, 018H and 019H).
Port 3 Interrupt Indication: Enabled when a 1 is written into the P3MSK
bit. A 1 indicates that an alarm has occurred in one of the port 3 alarm
registers for which the corresponding additional interrupt mask bit is also
set to 1 (addresses 017H, 018H and 019H).
Port 2 Interrupt Indication: Enabled when a 1 is written into the P2MSK
bit. A 1 indicates that an alarm has occurred in one of the port 2 alarm
registers for which the corresponding additional interrupt mask bit is also
set to 1 (addresses 017H, 018H and 019H).
Port 1 Interrupt Indication: Enabled when a 1 is written into the P1MSK
bit. A 1 indicates that an alarm has occurred in one of the port 1 alarm
registers for which the corresponding additional interrupt mask bit is also
set to 1 (addresses 017H, 018H and 019H).
