24 Test-Pattern Generation/Detection Functional Description
(continued)
CRC-4 errors (E1 multiframe only) are detected via TPM_CRCE2. Interrupts are managed via TPM_CRCE2M
(
Table 495
) bits. The global control signal SMPR_COR_COW determines if the TPM_CRCE2 event is cleared on
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 (
Table 498
) is asserted (default = 0, no AIS). A TPM_AISxD (
Table 487
) signal
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 (
Table 494
) is set.
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] (
Table 504
).
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] (
Table 518
and
Table 519
).
24.6.3 TPM Interrupts
The TPM block is capable of generating the following (maskable) interrupts:
Table 626. TPM Interrupts
The microprocessor interface may also read the current condition (status) of TPM framing, synchronization, or AIS
detection via the TPM_OOFx (
Table 496
), TPM_OOSx (
Table 497
), and TPM_AISx (
Table 498
) indicators directly.
