| * \par Purpose |
| * |
| * Interface for configuration the Pulse Width Modulation Controller (PWM) peripheral. |
| * |
| * \par Usage |
| * |
| * -# Configures PWM clocks A & B to run at the given frequencies using |
| * \ref PWMC_ConfigureClocks(). |
| * -# Configure PWMC channel using \ref PWMC_ConfigureChannel(), \ref PWMC_ConfigureChannelExt() |
| * \ref PWMC_SetPeriod(), \ref PWMC_SetDutyCycle() and \ref PWMC_SetDeadTime(). |
| * -# Enable & disable channel using \ref PWMC_EnableChannel() and |
| * \ref PWMC_DisableChannel(). |
| * -# Enable & disable the period interrupt for the given PWM channel using |
| * \ref PWMC_EnableChannelIt() and \ref PWMC_DisableChannelIt(). |
| * -# Enable & disable the selected interrupts sources on a PWMC peripheral |
| * using \ref PWMC_EnableIt() and \ref PWMC_DisableIt(). |
| * -# Control syncronous channel using \ref PWMC_ConfigureSyncChannel(), |
| * \ref PWMC_SetSyncChannelUpdatePeriod() and \ref PWMC_SetSyncChannelUpdateUnlock(). |
| * -# Control PWM override output using \ref PWMC_SetOverrideValue(), |
| * \ref PWMC_EnableOverrideOutput() and \ref PWMC_DisableOverrideOutput(). |
| * -# Send data through the transmitter using \ref PWMC_WriteBuffer(). |
