15.3.4 AMPM Input Pin
This analog pin is used as input for the operational amplifier negative input pin, if the according mode is
selected.
15.4 Memory Map and Register Definition
This sections provides the detailed information of all registers for the DAC_8B5V module.
15.4.1 _{Register Summary}
Figure 15-2 shows the summary of all implemented registers inside the DAC_8B5V module.
NOTE
Register Address = Module Base Address + Address Offset, where the
Module Base Address is defined at the MCU level and the Address Offset is
defined at the module level.
