4.13 Receive/Transmit Status
Table 4-10. Receive and Transmit Status Read Registers
The MPU may read all receive and transmit status registers non-destructively at any time. All status registers are
updated coincident with their respective HDSL channel’s receive or transmit 6 ms frame interrupts indicated in
the Interrupt Request Register [IRR; addr 0x1F]. Therefore, the MPU may poll the IRR or enable interrupts to
determine whether a status update has occurred. Real-time receive status (REOC, RIND, and RZBIT) register
updates are suspended when the respective HDSL channel’s receive framer reports an OUT_OF_SYNC state
[STATUS_1; addr 0x05].
