ADE7880 - Can't get HSDC data

I am new to ADE7880.


On my project, I need to get HSDC (high speed data capture) data. Now I can't get anything from HSDC interface, HSCLK pin stays at high, HSA pin is at high state all the time. I verified CLKIN is around 16 MHz.


Here is the set up upon the data sheet:


1. Configure MCU SPI port (I use PIC32) as the slave

2. Set HSDC_CFG (address 0xE706) register to 0x00

3. Set bit 6 of CONFIG to 1 to enable HSDC

    Load value 0x0042 to CONFIG register


I assume after above setting, HSDC interface should be enabled to send 16 registers out at 8KHz rate, is it right, anything missing?


Thank you very much for the help.
