Detailed Description

Fault Status Register (FAULT_STATUS)

Block 2, Address: 0x008

Reflects general system status flags for power and fault monitoring. Each bit indicates a specific fault or status condition. Bits are set and cleared automatically by hardware.

Register Map:

Bits	Name	Access	Reset	Description
12	LDO2_READY	R	0x0	LDO2 (V_EXT2) has completed soft-start (1 = ready)
11	LDO1_READY	R	0x0	LDO1 (V_EXT1) has completed soft-start (1 = ready)
10	VCCIO_UVLO	R	0x0	VCCIO undervoltage lockout detected
9	VDDA_UVLO	R	0x0	VDDA undervoltage lockout detected
8	VDD_UVLO	R	0x0	VDD undervoltage lockout detected
7	VSA_UVLO	R	0x0	VSA undervoltage lockout detected
6	CHGP_SHORT	R	0x0	VDRV charge pump short status
5	CHGP_OK	R	0x0	VDRV charge pump power-up is currently okay (1 =
OK) 4	LDOEXT2_SHORT	R	0x0	LDO2 (V_EXT2) is shorted 3

LDOEXT1_SHORT | R | 0x0 | LDO1 (V_EXT1) is shorted 2 | LDOEXT_TSD | R | 0x0 | LDO thermal shutdown status 1 | BCK_SHORT | R | 0x0 | VBUCK shorted 0 | BCK_UVLO | R | 0x0 | VBUCK undervoltage lockout detected

Note: All bits are read-only and reflect real-time hardware status.
