Read register from the OTP area of the Si7021 device.

Read register from the Hall sensor device.

Write a register in the Hall sensor device.

Set the given bit(s) in a register in the Hall sensor device.

Clear the given bit(s) in a register in the Hall sensor device.

Calculate the sw_op value from the threshold by finding the inverse of the formula: threshold = (16 + sw_op[3:0]) * 2^sw_op[6:4].

Calculate the sw_hyst value from the hysteresis by finding the inverse of the formula: hysteresis = (8 + sw_hyst[2:0]) * 2^sw_hyst[5:3].

Calculate the sw_tamper value from the tamper threshold by finding the inverse of the formula: tamper = (16 + sw_tamper[3:0]) * 2^(sw_tamper[5:4] + 5)

Calculate the slTime value from the sleep time by finding the inverse of the formula: tsleep = (32 + slTime[4:0]) * 2^(8 + slTime[7:5]) / 12 MHz.
