ICM-20601 configuring through FPGA

Hi all,
I using ICM-20601 IC for GYRO & Accelerometer data.I am configuring and reading data through SPI communication in FPGA,wheh i configured SPI clk as 2.5 Mhz from device i am unable to read correct data, then i clanged the SPI clk speed to 1 Mhz.I am able to read data, but it was not according to my device configuration.I configured device to +/-32g and tested by keeping the device is in stable Z-poisson so, i am expecting output of +/-1g data, but i am getting +/-4g as output.my configured registers are
regsister-6B data 09
6A data 11
6C data 00
1A data 00
1B data 00
1C data 18
1D data 10
