35 / 78 page  Preliminary Information MT9075A 4-163 Table 23 - Interrupt Mask Word One (Page 01H, Address 1CH) (continued) Bit Name Functional Description 7 SYNI Synchronization Interrupt. When unmasked (SYNI = 0) an interrupt is initiated when a loss of basic frame synchronization condition exists. Interrupt vector = 10000000. 6 RAII Remote Alarm Indication Interrupt. When unmasked (RAII = 0) a received RAI will initiate an interrupt. Interrupt vector = 01000000. 5 AISI Alarm Indication Signal Interrupt. When unmasked (AISI = 0) a received AIS will initiate an interrupt. Interrupt vector = 01000000. 4 AIS16I Channel 16 Alarm Indication Signal Interrupt. When unmasked (AIS16I = 0), a received AIS16 will initiate an interrupt. Interrupt vector = 01000000. 3 LOSI Loss of Signal Interrupt. When unmasked (LOSI = 0) an interrupt is initiated when a loss of signal condition exists. Interrupt vector = 01000000. 2 FERI Frame Error Interrupt. When unmasked (FERI = 0), an interrupt is initiated when an error in the frame alignment signal occurs. Interrupt vector = 00100000. 1 BPVO Bipolar Violation Counter Overflow Interrupt. When unmasked (BPVO = 0), an interrupt is initiated when the bipolar violation error counter changes form FFFFH to 0H. Interrupt vector = 00010000. 0 SLPI SLIP Interrupt. When unmasked (SLPI = 0), an interrupt is initiated when a controlled frame slip occurs. Interrupt vector = 00000100. Table 22 - Interrupt Mask Word Zero (Page 01H, Address 1BH) Bit Name Functional Description 7 EBI Receive E-bit Interrupt. When unmasked an interrupt is initiated when a receive E-bit indicates a remote CRC-4 error. 1 - unmasked, 0 - masked. Interrupt vector = 00100000. 6 CRCI CRC-4 Error Interrupt. When unmasked an interrupt is initiated when a local CRC-4 error occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000. 5 CEFI Consecutively Errored FASs Interrupt. When unmasked an interrupt is initiated when two consecutive errored frame alignment signals are received. 1 - unmasked, 0 - masked. Interrupt vector = 00100000. 4 BPVI Bipolar Violation Interrupt. When unmasked an interrupt is initiated when a bipolar violation error occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000. 3 RCR0I RAI and Continuous CRC Error Interrupt. When unmasked an interrupt is initiated when the received A bit has been one, and the received E bits have been zero, continuously for greater than 10 milliseconds (see page 04H, address 19H) 1- unmasked, 0 - masked. Interrupt vector = 00100000. 2 RCR1I RAI and Continuous CRC Error Interrupt. When unmasked an interrupt is initiated when the received A bit had been set, and the received E bits were low, continuously for greater than 10 milliseconds, but less than 450 milliseconds (see page 04H, address 19H). 1 - unmasked, 0 - masked. Interrupt vector = 00100000. 1 BERI Bit Error Interrupt. When unmasked an interrupt is initiated when a bit error occurs. 1 - unmasked, 0 - masked. Interrupt vector = 00100000. |
