4.10 Reset management
There are five kinds of reset: “pu”, “csb”, “sfpd”, “sfrst”, “sync”. “pu” is the most strong reset. It reset full chip.
“csb” reset the full chip, but retain the register setting. “sfpd” reset the sensor core, but I2C interface is live.
“sfrst” is an register signal. Every time it is programmed to “1”, all the I2C registers are reset. After that, it will
be reset to zero. “sync” reset the sensor core timing. To avoid the recovering time problem, clock oscillating is
designed to start a little time after “pu”, “csb” and “sfpd” reset is released.
