CCS/TMS320F28379D: fast current loop&pwm immediate update

Tool/software: Code Composer Studio

Hello:

The code related to the fast current loop at  ‘C:\ti\c2000\C2000Ware_MotorControl_SDK_3_00_00_00\solutions\tmdxiddk379d\f2837x’  is as follows:

FCL_initPWM(EPWM1_BASE, EPWM2_BASE, EPWM3_BASE);
#define EPWM1_BASE 0x00004000U // EPWM1
#define EPWM2_BASE 0x00004100U // EPWM2
#define EPWM3_BASE 0x00004200U // EPWM3

void FCL_initPWM(uint32_t baseA, uint32_t baseB, uint32_t baseC)
{
EPWM_disableCounterCompareShadowLoadMode(baseA, EPWM_COUNTER_COMPARE_A);
EPWM_disableCounterCompareShadowLoadMode(baseB, EPWM_COUNTER_COMPARE_A);
EPWM_disableCounterCompareShadowLoadMode(baseC, EPWM_COUNTER_COMPARE_A);
pwmCompA = (uint32_t *)(baseA + EPWM_O_CMPA);
pwmCompB = (uint32_t *)(baseB + EPWM_O_CMPA);
pwmCompC = (uint32_t *)(baseC + EPWM_O_CMPA);
return;
}
typedef enum
{
EPWM_COUNTER_COMPARE_A = 0, //!< counter compare A
EPWM_COUNTER_COMPARE_B = 2, //!< counter compare B
EPWM_COUNTER_COMPARE_C = 5, //!< counter compare C
EPWM_COUNTER_COMPARE_D = 7 //!< counter compare D
} EPWM_CounterCompareModule;

static inline void
EPWM_disableCounterCompareShadowLoadMode(uint32_t base,
EPWM_CounterCompareModule compModule)
{
uint16_t shadowModeOffset;
uint32_t registerOffset;

//
// Check the arguments
//
ASSERT(EPWM_isBaseValid(base));

if((compModule == EPWM_COUNTER_COMPARE_A) ||
(compModule == EPWM_COUNTER_COMPARE_C))
{
shadowModeOffset = 4U;
}
else
{
shadowModeOffset = 6U;
}

//
// Get the register offset. EPWM_O_CMPCTL for A&B or
// EPWM_O_CMPCTL2 for C&D
//
registerOffset = base + EPWM_O_CMPCTL + ((uint32_t)compModule & 0x1U);

//
// Disable shadow load mode.
//
HWREGH(registerOffset) = (HWREGH(registerOffset) |
(0x1U << shadowModeOffset));
}

Among them：base=0x00004000U,compModule=0，so, registerOffset=0x00004000U+0x8U+0，points to EPWM_CMPCTL_LOADAMODE, according to the comments of the code, shouldn't it point to EPWM_CMPCTL_SHDWAMODE, to activate pwm immediate update mode?

Is there anything wrong in my opinion？
