Description
Two PWM channels (channel
1 and channel 2) are configured to generate a 100kHz PWM signal. On channel
1, the signal is configured as left-aligned. On channel 2, the signal is center-aligned and the polarity is inverted.
On most Atmel evaluation kits, PWM signals for channels
1 and 2 are connected to two LEDs on the board. Since the duty cycle of the PWM signals varies continuously, the two LEDs will alternate between their minimum and maximum intensity. Note that on some
boards, only one LED will be connected.
