PWM, PDB, PGA, and ADC Connections
The comparators, timers, and PWM_reload_sync output can be connected to the programmable delay block (PDB) trigger input.
The PDB pre-trigger A and trigger A outputs are connected to the ADCA and PGA0 hardware trigger inputs. The PDB
pre-trigger B and trigger B outputs are connected to the ADCB and PGA1 hardware trigger inputs. When the input trigger of
PDB is asserted, PDB trigger and pre-trigger outputs are asserted after a delay of a pre-programmed period. See the MC56F8006
Peripheral Reference Manual for additional information.
