456 / 463 page  áç áç áç áç XRT7250 DS3/E3 FRAMER IC REV. 1.1.1 437 Whenever the Terminal Equipment encounters the Detection of FEBE Event Interrupt, it should do the following. • It should read the contents of the PMON FEBE Event Count Registers (located at Addresses 0x56 and 0x57) in order to determine the number of FEBE Events that have been received by the XRT7250 Framer IC. 6.3.6.2.9 The Detection of BIP-8 Error Interrupt If the Detection of BIP-8 Error Interrupt is enabled, then the XRT7250 Framer IC will generate an inter- rupt, anytime the Receive E3 Framer block has de- tected an error in the EM (Error Monitoring) byte, within an incoming E3 frame. Enabling and Disabling the Detection of FEBE Event Interrupt The user can enable or disable the Detection of BIP-8 Error’ interrupt by writing the appropriate value into Bit 2 (BIP-8 Interrupt Enable) within the Rx E3 Inter- rupt Enable Register - 2, as indicated below. Setting this bit-field to “1” enables this interrupt. Con- versely, setting this bit-field to “0” disables this inter- rupt. Servicing the Detection of the BIP-8 Error Inter- rupt Whenever the XRT7250 Framer IC detects this inter- rupt, it will do the following. • It will assert the Interrupt Request output pin (INT), by driving it “High”. • It will set the Bit 2 (BIP-8 Interrupt Status), within the RxE3 Interrupt Status Register - 2 as indicated below. Whenever the Terminal Equipment encounters the Detection of BIP-8 Error Interrupt, it should do the fol- lowing.
