CLASSC_ESC_CNT . CLASSC_ESC_CNT

Returns the current timeout or escalation count (depending on CLASSC_STATE). This register can not be directly cleared. However, SW can indirectly clear as follows.

If the class is in the Timeout state, the timeout can be aborted by clearing the corresponding interrupt bit.

If this class is in any of the escalation phases (e.g. Phase0), escalation protocol can be aborted by writing to CLASSC_CLR_SHADOWED. Note however that has no effect if CLASSC_REGWEN is set to false (either by SW or by HW via the CLASSC_CTRL_SHADOWED.LOCK feature).
