Definition
Current capability
1: Reduced current mode (all gate charge/discharge currents are 25%)
0: Full current mode
Loss of clock detection test/VS comparator test
If this bit is set, the clock for LOC monitor is permanently set to high. Additionally, the VS comparators
show a VS undervoltage and a VS overvoltage at the same time in status register 1 (STAT1), bits 1:0.
Both LOC and VS undervoltage/overvoltage are indicated on the ERR pin. A way to distinguish
between LOC and VS undervoltage/overvoltage is described in VS Comparator Check.
Once the bit is cleared, the error-flag disappears after read out.
