REGISTER DESCRIPTIONS (cont.)

SENSOR OUTPUT STATUS REGISTER: SO<31:0>

THIS 32 BIT REGISTER IS ACCESSED BY THE FOLLOWING 5 SPI COMMANDS

For GND/Open inputs, SO<n> = “0” if the SENSE<n> pin is open or > VTHI

SO<n> = “1” if the SENSE<n> pin is <= VTLO

For Supply/Open inputs, SO<n> = “1” if the SENSE<n> pin is open or < VTLO

SO<n> = “0” if the SENSE<n> pin is >= VTHI

SENSOR STATUS BANK 0 REGISTER: SO<7:0>
