Integration

Global Data

The following global symbols must be defined in CDD_Data.c and .h (populated by PwmCdd):

uint16: CDD_DCPhsComp_Cnt_G_u16[3]
uint16: CDD_PWMPeriod_Cnt_G_u16

Component Conflicts

Project Specific

NHET/EPWM version corresponding PWMCdd component spilt and using global variables CDD_DCPhsComp_Cnt_G_u16 and CDD_PWMPeriod_Cnt_G_u16 should be used.

Include Path

The “include” directory of this SWC needs to be included in the integration project include search path.

Runnable Scheduling

This section specifies the required runnable scheduling.

Runnable	Scheduling Requirements	Trigger
PwmCdd_Init	Place in EcuStartup. Execute along with NHET initialization.	Init
PwmCdd_Per1	Must be placed in the motor control ISR, before Nhet (or whichever function populates the global variables used byNhet).	Cyclic (ISR) *

*Note: don’t forget include header file from PWMCDD where PwmCdd_Per1 is called
