state. This stretch time can be selected by setting the ID[1:0] bits in the SampleID register
according to following table.
Table 6.
When nRST_int becomes active (logic level = “0”) it sets in their reset state some of the
functions inside L6460. The main functions that will be reset by nRST_int signal are the
following:
Additionally the system regulators will be powered off but only if the voltage that caused the
nRST_int event is checked before the system regulator in the power up sequence. This
means that:

Serial interface will be reset and will not accept any other command.
The bridges 1 and 2 will place their outputs in high impedance and PWM and
direction signals will be reset.
AD converter will be powered off.
GPIOs will be powered off.
Current DAC will be powered off.
Operational amplifiers will be powered off.
Watchdog count will be reset (while Watchdog flags won’t be reset).
Interrupt controller will be powered off.
Digital comparator will be powered off.
all system regulators will be powered off if nRST_int is caused by V
V
no one of the system regulators will be powered off if nRST_int is caused by
V
only the system regulators that follows the system regulator that caused the
nRST_int in power up sequence will be powered off.
