ADS7953: Powerup sequence information missing for DI05 bit set power down method

Sundara Ramanan M A

Part Number: ADS7953

I am currently using ADS7953 chip in data acquisition and we are lookin at ways for powerdown and powerup.As I looked at the Datasheet I found that there are two methods to do it
Method 1 involves just setting DI05 bit in mode control register and the Chip will be powered down at the 16th falling edge clk of the next data frame.
Method 2 involves controlling thru GPIO 3 pin reset .
Method 2 has a clear procedure for powering up on CS falling edge with DI05 0 in the mode control register and GPIO3 is set to high .

So what is the procedure to Powerup the chip when only using the DI05 bit set power down method

Thanks

Hello,

when using the DIO5 to power down the device, to power up again, this register needs to be cleared

A falling CS edge followed by clearing DIO5 will power up the device, the device will be awake in the 16th falling edge of SCLK in the next data frame
