Enabling and Disabling the Detection of Payload Type Mismatch Interrupt. The user can enable or disable the Detection of Pay- load Type Mismatch Interrupt by writing the appropri- ate data into Bit 0 (RxPld Mis Interrupt Enable), within the Rx E3 Interrupt Enable Register - 2, as indicated below. Setting this bit-field to “1 enables the Detection of Payload Type Mismatch Interrupt. Conversely, setting this bit-field to “0” disables the Detection of Payload Type Mismatch Interrupt. Servicing the Detection of Payload Type Mis- match Interrupt Whenever the XRT7250 Framer IC generates this in- terrupt, it will do the following. • It will assert the Interrupt Request output pin (INT) by driving it “Low”. • It will set Bit 0 (RxPld Mis Interrupt Status), within the Rx E3 Interrupt Enable Register -2 to “1”, as indicated below. 6.3.6.2.12 The Receive LAPD Message Interrupt If the Receive LAPD Message Interrupt is enabled, then the XRT7250 Framer IC will generate an inter- rupt anytime the Receive HDLC Controller block has received a new LAPD Message frame from the Re- mote Terminal Equipment, and has stored the con- tents of this message into the Receive LAPD Mes- sage buffer. Enabling/Disabling the Receive LAPD Message Interrupt The user can enable or disable the Receive LAPD Message Interrupt by writing the appropriate data into Bit 1 (RxLAPD Interrupt Enable) within the Rx E3 LAPD Control Register, as indicated below.
