1 = FEN1 input or FEN1 latch timer active

Note:

The FEN status is the result of the state of the FEN input pin OR’d with the FEN latch timer.

The FEN latch timer will remain inactive until a transition of ‘1’ to ‘0’ on the FEN input

(assuming the pin was high for a minimum of 16μs). At that time the FEN latch timer will be

active and keep the internal FEN signal active based on the programmed time (0ms, 128ms,

256ms or 512ms) for that particular FEN function.

With Bit D9 = 2

Bit D7:

0 = Current through channel 7 is below IMEAS

1 = Current through channel 7 is above IMEAS

Bit D6:

0 = Current through channel 6 is below IMEAS

1 = Current through channel 6 is above IMEAS

Bit D5:

0 = Current through channel 5 is below IMEAS

1 = Current through channel 5 is above IMEAS

Bit D4:

0 = Current through channel 4 is below IMEAS

1 = Current through channel 4 is above IMEAS

Bit D3:

0 = Current through channel 3 is below IMEAS

1 = Current through channel 3 is above IMEAS

Bit D2:

0 = Current through channel 2 is below IMEAS

1 = Current through channel 2 is above IMEAS

Bit D1:

0 = Current through channel 1 is below IMEAS

1 = Current through channel 1 is above IMEAS

Bit D0:

0 = Current through channel 0 is below IMEAS

1 = Current through channel 0 is above IMEAS

Note:

current status for channel is captured on the falling edge of chip select
