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.
