We are facing some problems initializing the device and also looking to put the device in low power-down mode.
We are planning to use the reset to reinitialize if the 1st initialization fails.
I have checked the datasheet and could not find any information with regards to RESET timing specifications.
According to datasheet Powering up time take about 260ms.
So if we use a RESET pulse of 25ns*16 =400ns (16 SCLK of SPI where CS is low ) which is similar to writing to 0x00 register is it fine.
After the reset pulse wait for 260ms and then start with the device set up using SPI.
With best regards
