. These DACs can be set by using the stdm instruction to setup the access
mode. The DAC registers can be loaded with the cp and load instructions. Loading DAC
register values to other registers or DRAM is also possible by means of the cp and store
instructions.

2.15 Output drivers
The instructions described in this section are used to control the output drivers. Each
high-side and low-side can be turned ON/OFF by all microcores if the output access
registers are configured properly (refer to register 184h to 187h). Low-side and high-side
bias needs to be enabled before using the diagnostics, and can be kept ON during the
application.
It is possible to enable or disable the end-of-actuation mode. In the final phase of an
actuation, while the current in the actuator is decreasing, it is possible to detect when
the current has reached the zero value. In most applications, it is required that the
Vsource threshold for the corresponding HS output is set to zero. This condition can be
automatically enabled and disabled together with the end-of-actuation mode.
