General Interrupt Enable Register
Address: 1B
Abbreviation: GENINTEN
Read/Write
General Interrupt Vector Status
All of the HDSL overhead status bits in this register are latched active High when detected, and
remain High until a write is done by the microprocessor. When a logic
1
is written to these
registers, these status bits are cleared unless the associated overhead bit is still active.
Address: 1C
Abbreviation: GENINTSTAT
