condition still exists, a wrong
load can be assumed.
If the PWM1/2 Enable Bit is set
and the output is enabled
(Input Register 0) the output is
switched on if PWM1/2 input is
high and switched off if
PWM1/2 input is low. OUT7 is
controlled by PWM2 input. All
other outputs are controlled by
PWM1 input. For test mode
rise CSN>9.5 V.

Status register 1 (read)
The open load detection
monitors the load current
in each activated output
stage. If the load current
is below the open load
detection threshold for at
least 1 ms (t
corresponding open load
bit is set. Due to
mechanical/electrical
inertia of typical loads a
short activation of the
outputs (e.g. 3ms) can
be used to test the open
load status without
changing the
mechanical/electrical
state of the loads.
A logical NOR-
combination of all bits 1
to 22 in both status
registers.
