| /// !Purpose | |
| /// | |
| /// Interface for configuration the Pulse Width Modulation Controller (PWM) peripheral. | |
| /// | |
| /// !Usage | |
| /// | |
| /// -# Configures PWM clocks A & B to run at the given frequencies using | |
| /// PWMC_ConfigureClocks(). | |
| /// -# Configure PWMC channel using PWMC_ConfigureChannel(), PWMC_SetPeriod() | |
| /// and PWMC_SetDutyCycle(). | |
| /// -# Enable & disable channel using PWMC_EnableChannel() and | |
| /// PWMC_DisableChannel(). | |
| /// -# Enable & disable the period interrupt for the given PWM channel using | |
| /// PWMC_EnableChannelIt() and PWMC_DisableChannelIt(). | |
| /// | |
| /// Please refer to the list of functions in the #Overview# tab of this unit | |
| /// for more detailed information. | |
