μs

Not subject to production test

Note:

All parameters are guaranteed, and tested, in the voltage ranges specified above in Table 5 unless otherwise

specified. Where not specified the parametrical operating range equals the functional operating range.

Note:

•

In case of BIST_STATUS=11 (BIST check failure) the device sent in SAFE_OFF Mode, re-engage

procedure can be performed only by issuing a SW_REST command.

•

In case of WDT_OVF_fail = 1 or WDT_DATA_fail = 1 (WDT failure) the device sent in SAFE_OFF Mode,

re-engage procedure can be performed only by issuing a WDT_RST or a SW_REST command.
