EVENT LOGGER SEQUENCES

The CS47L85 provides 8 Event Log functions, for monitoring and recording internal or external signals. The logged events

are held in a FIFO buffer, from which the application software can read details of the detected logic transitions.

The Control Write Sequencer is automatically triggered whenever the NOT_EMPTY status of the Event Log buffer is

asserted. A different control sequence may be configured for each of the Event Loggers.

The WSEQ_EVENTLOGn_INDEX register defines the sequencer start index corresponding to respective Event Logger

(where ‘n’ is 1 to 8), as described in Table 123.

Note that a sequencer start index of 1FFh will cause the respective sequence to be aborted.

The Event Logger control sequences are undefined following Power-On Reset (POR), Hardware Reset, or following a Sleep

mode transition. The Event Logger control sequences must be reconfigured by the host processor following any of these

events. Note that all control sequences are maintained in the sequencer memory through Software Reset.

See “DSP Peripheral Control” for further details of the Event Loggers.
