Table 12. OSS SPI Control Commands and Response
ON /OFF CONTROL COMMAND
bit serial stream of data is entered into the SI pin. The first 8-
bits of the control word are used to identify the on / off
command and the remaining 8-bits are used to turn ON or
OFF the specific output driver. When commanding an output
ON or OFF, the Most Significant Bit (MSB) is sent and
received first. Bit 7 corresponds to output 8 down to bit 0
which corresponds to output 1.
OPEN LOAD CURRENT ENABLE COMMAND
disable the open load detect pull-down current. This feature
allows the device to be used in LED applications. On power
up reset (POR) or the RESET command the pull-down
current sources are disabled. To enable the open load
current source, the user must program the Open Load
Current Disable Control register with logic[1]. Open load

OVER-VOLTAGE SHUTDOWN/RETRY COMMAND

voltage control bit sets the operation of the outputs when
returning from over-voltage. Setting the over-voltage bit to
logic[0] will force all outputs to remain OFF when V
returns to normal level. Setting the over-voltage bit to logic[1]
will command outputs to resume their previous state when
