Analog-to-Digital Converter (ADC16)
21.1
The 16-bit analog-to-digital converter (ADC) is a successive approximation ADC designed for operation
within an integrated microcontroller system-on-chip.
21.1.1
The bus clock to each ADC can be gated on and off using the SCGC1_ADCx bits (see
“System Clock Gating Control 1 Register
bus clock to this module. To conserve power, the SCGC1_ADCx can be cleared to disable the clock to this
module when not in use. See
21.1.2
The hardware triggers of ADC1, ADC2, ADC3 and ADC4 are provided from PDB channel 1, 2, 3 and 4
correspondingly, when ADTRG is set in ADCxSC2.
When enabled, ADCx will be triggered every time PDB channel x TriggerA output is asserted. The PDB
channel x PreTriggerA and PreTriggerB will set the ADHWTSA and ADHWTSB correspondingly.
For details on ADC hardware trigger function, refer to
Selects”. For details on PDB, refer
