Device Overview MC9S12VR-Family
1.14
The ADC module includes external trigger inputs ETRIG0, ETRIG1, ETRIG2, and ETRIG3. The external
trigger allows the user to synchronize ADC conversion to external trigger events. ETRIG0 is connected to
PP0 / PWM0 and ETRIG1 is connected to PP1 / PWM1. ETRIG2 and ETRIG3 are not used .ETRIG0 can
be routed to PS2 and ETRIG1 can be routed to PS3.
1.15
Whenever the ADC’s Special Channel Conversion Bit (SC) in 8.3.2.6 ATD Control Register 5 (ATDCTL5)
is set, it is capable of running conversion on a number of internal channels.
sources which are connected to these special conversion channels.
