• 12-channel Direct Memory Access Controller (DMAC)
• 12-channel Event System
• Up to eight 16-bit Timer/Counters (TC), configurable as either (see Note):
Note: Maximum and minimum capture is only available in the SAM C21N devices.
– One 16-bit TC with compare/capture channels
– One 8-bit TC with compare/capture channels
– One 32-bit TC with compare/capture channels, by using two TCs
• Two 24-bit and one 16-bit Timer/Counter for Control (TCC), with extended functions:
– Up to eight PWM channels on each 24-bit TCC
– Up to two PWM channels on each 16-bit TCC
– Up to four compare channels with optional complementary output
– Generation of synchronized pulse width modulation (PWM) pattern across port pins
