The second sequence timer (SST) is an additional timer that can be used to delay the inevitable watchdog timer reset. This delay can be useful in applications where software needs to log the data for debug work.

The SST can be enabled in basic and Q&A window modes.

When the second sequence timer is enabled, the xxx_SWDT_INT_PEND system interrupt signal and the SWDTn_RST_PEND output signal to the MIO/EMIO remain asserted until the watchdog timer is reset.
