Description
Analog watchdog enable
0 The analog watchdog related to the algorithm S (step 2) is disabled
1 The analog watchdog related to the algorithm S (step 2) is enabled
Low threshold value for channel n (unsigned coding). If the analog watchdog is enabled, the
STSR1[ERR_S2] status bit is set if STDR1[TCDATA] <THRL.
