SAM4S Series [DATASHEET]
11100F–ATARM–29-Jan-14
 Synchronous Channels Supports Connection of one Peripheral DMA Controller Channel (PDC) Which
Offers Buffer Transfer Without Processor Intervention To Update Duty-Cycle Registers
 2 Independent Events Lines Intended to Synchronize ADC Conversions
 Programmable delay for Events Lines to delay ADC measurements
 8 Comparison Units Intended to Generate Interrupts, Pulses on Event Lines and PDC Transfer Requests
 8 Programmable Fault/Break Inputs Providing an Asynchronous Protection of PWM Outputs
 3 User Driven through PIO inputs
 PMC Driven when Crystal Oscillator Clock Fails
 ADC Controller Driven through Configurable Comparison Function
 Analog Comparator Controller Driven
 Timer/Counter Driven through Configurable Comparison Function
 Write Protected Registers
