This config tool simplifies PLL setting calculation and clock configuration for MPC5744P device. Follow these steps Note: Macros have to be enabled! 1. Enter frequency of used XOSC and desired PLL0 and PLL1 output. - put values into cells B11, Q10 and Q17 of the "Clocks" sheet - check if it is Valid or Invalid - "PLLconfig" sheet shows possible PLLs configurations 2. Configure System and AUX clock selectors and its Dividers - check calculated frequency of System/Peripheral clocks - if Invalid change source clock and Divider value to keep Max freq 3. Copy generated code by pressing "Copy Code" button

******************************************************************************** * Detailed Description: * * * This example shows usage of FlexPWM and Sine Wave generator (SGEN) modules. * The setting is selected in the way to have a PWM output signal synhronized with * SWG output signal. This is necessary for resolver usage in motor control appls. * The CTU_0 is triggered from FlexPWM_0's. The PMWB output rising edge is used here. * The CTU generates the eTIMER1_TRG signal, that is a trigger signal for the * SGEN module. The delay between PWMB and SGEN trigger is changed so you can see * the generated sinusoidal signal change phase against the PWMB output. * * See attached Excel sheet for calculation of parammeters used here (AUX0_clk_DIV0, * AUX0_clk_DIV1, SGEN_IOFREQ, PWM_PRESCALER, PWM_MODULO). * * This example is set for 9.765625KHz SGEN/PWM frequency. * * Note because the SGEN trigger input is an asynchronous signal, it must be held high * for at least 2 SGEN clock cycles in order to capture the input trigger. * As the CTU generates the trigger as a pulse of single CTU clock width, the CTU clock must be * half of the SGEN clock at least. * * Use the AUX0_clk_DIV0 to test this behaviour. * * * ------------------------------------------------------------------------------ * Test HW: MPC57xx * Maskset: 1N65H * Target : internal_FLASH * Fsys: 200 MHz PLL with 40 MHz crystal reference * * EVB connection: * * P11.8 - D[7] ..
