TC compare mode

This example shows how to use the TC module in compare mode to generate an active low, active high, and toggle output on compare match.

Description

Three TC channels are configured in compare mode. Each channel generates different output waveform depending upon configured action on compare match and period match.

Active low output: Output is set high on compare 1 match and is set low on compare 0 match.

Active high output: Output is set low on compare 1 match and is set high on compare 0 match.

Toggle output: Output toggles on compare 0 match.

Setting up SAM HA1G16A Xplained Pro Evaluation Kit

• Connect the Debug USB port on the board to the computer using a micro USB cable

Note:

ATSAMHA1G16A device in SAM HA1G16A Xplained Pro board is not recommended for new design, hence replace the device with ATSAMHA1G16AB device. Connect the supported external debugger to Cortex Debug Port
