Bits OD3:OD0 reflect the current state of the Fault register
(FLTR) corresponding to the output previously selected with
the bits A1A0 (Table 17).
Data returned in bits OD3:OD0 are programmed current
values for the over-current high detection level (refer to
Table 12, page 23) and the over-current low detection level
(refer to Table 11, page 23), corresponding to the output
previously selected with A1A0.

The returned data contains the programmed values in the
CDTOLR register for the output selected with A1A0.
s =Selection of the output.
Note The FS pin reports all faults. For latched faults, this
pin is reset by a new Switch OFF command (via SPI or direct
input IN).

Data in bits OD3:OD0 contains IN3_SPI:IN0_SPI
programmed bits for outputs HS3:HS0, respectively.
PREVIOUS ADDRESS SOA4:SOA0=00101
The returned data contains the programmed values in the
UOVR register.
PREVIOUS ADDRESS SOA4:SOA0=01001
Data in bits OD3:OD0 contains the programmed
CSNS3 EN:CSNS0 EN bits for outputs HS3:HS0,
respectively.
PREVIOUS ADDRESS SOA4:SOA0=01101
The returned data contains the programmed values in the
WDR register. Bit OD2 (WDTO) reflects the status of the
