Block Description and Electrical Characteristics
When the undervoltage condition at U_ST or U_ZP is no longer detected a reset reaction
time of typical 52 ms (52 clock cycles) is started. After this time the reset signal is set
high.
Table 1
Truth Table Overvoltage and Undervoltage Supervision
The table assumes that no other error is detected, especially no watchdog failure and no
clock failure.
