Legend:

r = Reserved bit

RoR = Reset-on-Read bit

R = Readable bit

W = Writable bit

U = Unimplemented bit, read as ‘0’

-n = Value at POR

‘1’ = Bit is set

‘0’ = Bit is cleared

x = Bit is unknown

bit 7

FLT: Fault flag bit (latched)

FLT is set to ‘1’ if HICCUP = 1 or if (ENS = 1 and SSD = 1 and POK = 0).

bit 6

HICCUP: Hiccup Flag bit (latched)

If the HS OC event counter reaches EOC and POK is low, the HICCUP flag is latched. The behavior

of the system is determined by the HCPEN bit.

bit 5

ILIMNEG: Negative Current Limit Flag bit (latched)

If the negative current limit threshold is reached, the ILIMNEG flag is latched.

bit 4

ZCD: Zero Current Crossing Detection Flag bit (latched)

This bit is set every time the ZCD is enabled (in Auto-PFM mode) and the ZCD comparator trips.

bit 3

Reserved: Maintain as ‘0’

bit 2

SSD: Soft Start Done Status bit (not latched)

SSD = 1 means the regulator is enabled and has completed the soft start ramp.

bit 1

POK: Power OK Status bit (not latched)

POK reflects the instantaneous value of the POK comparator output.

bit 0

ENS: Enable Status bit (not latched)

ENS = 1 means the regulator is currently enabled.
