Des — OP_LOW — Optional
The OP_LOW feature is used to hold the LVCMOS outputs,
except for the LOCK output, at a LOW state. When the
OP_LOW feature is enabled, the LVCMOS outputs will be
held at logic LOW while LOCK = LOW. The user must toggle
the OP_LOW Set/Reset register bit to release the outputs to
the normal toggling state. Note that the release of the outputs
can only occur when LOCK is HIGH. The OP_LOW strap op-
tion is assigned to the PASS pin, at pin location 42.
Restrictions on other straps:
1.
Other strap options should not be used in order to keep
the data and clock outputs at a true logic LOW state.

2.
Outputs DO[23:0], CO[3:1] and CLKOUT are in TRI-STATE™
before PDB toggles HIGH because the OP-LOW strap value
has not been recognized until the DS92LV2412 powers up.

reset of OP_LOW can only occur when LOCK is HIGH.
Other features should be selected through the I2C
register interface.
The OSS_SEL feature is not available when OP_LOW is
enabled.
