SAM4S Series [Preliminary]

• Write Protect Registers

• Programmable Schmitt trigger inputs

• Parallel capture mode

– Can be used to interface a CMOS digital image sensor, an ADC....

– One clock, 8-bit parallel data and two data enable on I/O lines

– Data can be sampled one time out of two (for chrominance sampling only)

– Supports connection of one Peripheral DMA Controller channel (PDC) which offers

buffer reception without processor intervention

10.15 Peripheral Identifiers

Table 10-3 defines the Peripheral Identifiers of the SAM4S. A peripheral identifier is required for

the control of the peripheral interrupt with the Nested Vectored Interrupt Controller and control of

the peripheral clock with the Power Management Controller.
