17 help
18 This option enables device driver support for the PWMC
19 peripheral channels found on certain Atmel processors.
20 Pulse Width Modulation is used many for purposes, including
21 software controlled power-efficient backlights on LCD
22 displays, motor control, and waveform generation. If
23 unsure, say N.
