AS7261 − Detailed Descriptions

4-Btye Floating-Point (FP) Registers

Several 4 byte registers (hex) are used by the AS7261. Here is

an example of how these registers are used to represent floating

point data (based on the IEEE 754 standard):

Figure 20:

Example of the IEEE 754 Standard

The floating point (FP) value assumed by 32 bit binary32 data

with a biased exponent e (the 8 bit unsigned integer) and a

23 bit fraction is (for the above example):
