Detailed Description

The main oscillator initialization configures the internal PLL to boost the user-defined source clock to the desired operating frequency (e.g. 100 MHz for dsPIC33CK).

Function Documentation

◆ sysAclk_Initialize()

uint16_t sysAclk_Initialize ( void )

Initializes the auxiliary clock of the device.

Returns: unsigned integer (0=failure, 1=success)

This function initializes the auxiliary PLL for operating ADC and PWM module at maximum performance at an input clock of 500 MHz. Each peripheral module may use additional frequency scalers and multipliers to further convert this frequency.

◆ sysFosc_Initialize()

uint16_t sysFosc_Initialize ( void )

System oscillator initialization.

Returns: unsigned integer 0=failure 1=success

This function initializes the internal 8 MHz RC oscillator as the main oscillator and initializes the PLL to operate the CPU at maximum performance of 100 MHz instruction cycle.
