◆ CLOCK_GetPeripheralChannelFreq()

uint32_t CLOCK_GetPeripheralChannelFreq ( uint32_t peripheral_channel_id )

Fetches the clock frequency for a specific peripheral channel in Hz.

This function calculates and returns the frequency of a peripheral channel (GCLK peripheral control) by reading the assigned GCLK generator, its source, and division settings. It uses existing PLIB GCLK and OSCCTRL APIs to determine the actual frequency.

Parameters

peripheral_channel_id The peripheral channel ID (e.g., SERCOM0_GCLK_ID_CORE, TC0_GCLK_ID). This must be a valid peripheral channel identifier from the device header.

Note: The peripheral channel must be enabled (via GCLK_EnablePeripheralChannel) and properly configured before calling this function. If the channel is disabled, this function may return 0.
