Interfaces of the ADC Module
The ADC is connected to its environment in different ways.
Internal Connections
The capture/compare signal CC31IO of the CAPCOM2 unit is connected to the ADC,
providing an optional trigger source for injected conversions.
The 2 interrupt request lines of the ADC are connected to the interrupt control block.
External Connections
The analog input signals for the ADC are connected with Port 5 of the XC161 (input
only). Two dedicated pins (VAREF and VAGND) provide the analog reference voltage for the
conversion mechanism.
