inlinestatic

The user specifies which signal to modify by supplying the submodule number and whether to modify the PWM A or the PWM B within that submodule.

Parameters

base	Base address pointer of eflexPWM module
subModuleNum	is a number of the PWM submodule.
output	specifies which signal to work with in the module, 0 is PWM B, 1 is PWM A
val	true to supply a logic 1, false to supply a logic 0.

static void PWM_HAL_SetPwmRunCmd ( PWM_Type *  base, uint8_t  subModules, bool  val  )

inlinestatic

Parameters

base	Base address pointer of eflexPWM module
subModules	represented by corresponded bits.
val	true to run selected subModuleNums, false to stop selected subModuleNums output.
