Enable "Multipoint Phase/Gain Calibration" fail, why?

Question

I try to set MTEN bit in config0 register for ADE9430, when system initialization. but I can see any different Irms with MTEN=0, It seems the MTEN is invalid. The code see below: 
 
 config = 0;

AFEWrite16BitReg(REG_RUN, (uint16_t *)&config); 
 
 config = BITM_CONFIG0_RMS_SRC_SEL | BITM_CONFIG0_PERIOD_AVG_CFG_AV16 | BITM_CONFIG0_MTEN; 
 AFEWrite32BitReg(REG_CONFIG0, (uint32_t *)&config);

config = 1 ;

AFEWrite16BitReg(REG_RUN, (uint16_t *)&config); 
 
 Is there any other points I missed? 
 
 Thanks! 
 Kevin

According to the user manual, you need to set MTEN=1 to enable the current channel gain and phase compensation.)
