Description
Fault flag bits of the following conditions;⁽²⁾
MTOC: Motor overcurrent. (OVAD)
VCCOC: VCC overcurrent
VCCOV: VCC overvoltage
VDDOV: VDD overvoltage
CPOV: Charge-pump overvoltage
CPUV: Charge-pump undervoltage
VBOV: VB overvoltage
VBUV: VB undervoltage
If FLTCFG.FLGLATCH_EN = 1
0: Read = No fault condition exists since last cleared.
Write = No effect
1: Read = Fault condition exists.
Write = Clear the flag.
If FLTCFG.FLGLATCH_EN = 0
0: Read = No fault condition
Write = No effect
1: Read = Fault condition
Write = No effect
(1) R: Read, W: Write
(2) Assertion of the fault flags may occur during power up.
