1.40.24.66 TCCx_PWM32bitPeriodSet Function

C

/* x = TCC instance number */
void TCCx_PWM32bitPeriodSet ( uint32_t period );

Summary

Sets the period value of a given TCC instance.

Description

This function writes the period value. Period value is shared between all the channels of TCC instance. When counter matches period value interrupt can be generated. This function writes to the double buffered register. Actual update happens on period match or zero match.

Precondition

TCCx_PWMInitialize and TCCx_PWMStart functions must have been called first for the given channel.

Parameters

Returns

None.

Example

TCC0_PWMInitialize();
TCC0_PWMStart();
TCC0_PWM32bitPeriodSet(0x500ul);

Remarks

This function waits till sync operation is complete. TCC should be running to write to double buffered period register.
