Forum Post: AFE5801- SPI Reset Command, 16 or 24 bit

$

Hello:

Could you please explain how to send SPI Reset & Mutiple Register Write commands to AFE5801?  pg. 20 of the AFE5801 datasheet mentions a SOFTWARE_RESET function. 1 resets the device. pg. 19 of the AFE5801 datasheet states register address is 8 bits ( A0....), data is 16 bits,(D0....). Would a SPI Reset command be sent as 24 bits (i.e. 0000 0000 0000 0000 0000 0000) to AFE5801? What would be the address? I assume it would be a 8 bit hexadecimal number (01h, 05h etc.)

e.g. the SPI Reset command for ADS1258 is 110 (pg. 35 of the ADS1258 datasheet), Multiple Register command is 0111 (pg. 32 of the ADS1258  datasheet). Assuming 8 bits, I would send 11000000 to reset SPI bus
in ADS1258. Hopefully, this explains what I am asking for.

My goal is to write several register values to AFE5801 as a 1D array.

Thank you.

Best Regards,

Mohit
