SAM7SE512/256/32
⢠Offers a configurable frame sync and data length
⢠Receiver and transmitter can be programmed to start automatically or on detection of
different event on the frame sync signal
⢠Receiver and transmitter include a data signal, a clock signal and a frame synchronization
signal
10.11 Timer Counter
⢠Three 16-bit Timer Counter Channels
â Two output compare or one input capture per channel
⢠Wide range of functions including:
â Frequency measurement
â Event counting
â Interval measurement
