24 Test-Pattern Generation/Detection Functional Description
CRC-4 errors (E1 multiframe only) are detected via TPM_CRCE2. Interrupts are managed via TPM_CRCE2M
(Table
read or write.
TPM Data AIS Detection. If an active data monitor detects AIS (i.e., detects all ones in the data signal), the corre-
sponding register bit TPM_AISx
detects and latches delta events (changes or transitions) in the TPM_AISx signal. The TPM_AISxD signal is reset
to 0 based on the SMPR_COR_COW global control signal: if SMPR_COR_COW is set, event or delta signals are
cleared on any microprocessor read of the event or delta register. If SMPR_COR_COW is 0, each event or delta
signal must be written with a 1 to clear it. The TPM_AISxD signal, if asserted, will trigger an interrupt unless the
corresponding interrupt mask bit TPM_AISxDM
TPM DS1-ESF Data Link. For DS1 extended super frame (ESF) test patterns, the received data link field contents
are presented to software via registers entitled TPM_ESFDL[15:0] (
TPM E1 Sa-Bits Field. For E1 framed test patterns, the received Sa bits are presented to software via registers
entitled TPM_E1SAx[4:8]
24.6.3 TPM Interrupts
The TPM block is capable of generating the following (maskable) interrupts:

The microprocessor interface may also read the current condition (status) of TPM framing, synchronization, or AIS
detection via the TPM_OOFx
