Note:
If a digital device and no detailed diagnosis is selected, also ambiguous failures are
reflected in this register (channel is turned off if ASDT is selected).
Note:
1
In digital mode, the OL failure can not be cleared in off-state when detailed diagnosis is
disabled. To clear the OL bit, the detailed diagnosis has to be enabled or the failure has to
be removed and cleared in on-state.
2
If a digital device and no detailed diagnosis is selected, also ambiguous failures are
reflected in this register.

CLK_IN0 Warn, CLK_IN1 Warn: the corresponding warn bit is set when the input frequency
is below 5kHz (fPWMmin_set = 19 Hz) and reset when the frequency is above 7 kHz
fPWMmin_reset = 28 Hz. The hysteresis was implemented not to get a flickering on the PWM
output. If the warn bit is set the PWM is generated by an internally generated signal
(f = 122 Hz). The warn bit does not set the global error flag.
CLK_INx Warn 0
input clock frequency fCLK_INx > 7 kHz.
1
input clock frequency fCLK_INx < 5 kHz (fPWMmin < 19 Hz). The internal
generated PWM clock signal is used.
CS_timeout
this bit is set when a CS-timeout occurred. It has to be cleared by a clear
command (Op code b10)
CS_time50%
this bit is set when 50% of the CS-timeout time is reached.
