SAM3S8/SD8 Summary
– Lock of the configuration by the connected peripheral
• Synchronous output, provides set and clear of several I/O lines in a single write
• 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
10.16 Peripheral Identifiers
Table 10-3 defines the Peripheral Identifiers of the SAM3S8/SD8. 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.
