Register description
Register interpreter
Register contents represent different data types as described in
Table 4.
Registers not listed in this datasheet should be considered as reserved or read-only and
should not be written to, as this may cause unpredictable results.
The VL6522 registers can be written to using the extension units within the Windows video
class.
All register locations contain an 8-bit byte. However, certain parameters require 16 bits to
represent them and are therefore stored in more than 1 location.
For all 16 bit parameters, the MSB register must be written before the LSB register.
The data stored in each location can be interpreted in different ways as shown below.
Register contents represent different data types as described in
Table 5.
Float number format
Float 900 is used in ST co-processors to represent floating point numbers in 2 bytes of data.
It conforms to the following structure:
Bit[15] = Sign bit (1 represents negative)
Bit[14:9] = 6 bits of exponent, biased at decimal 31
Bit[8:0] = 9 bits of mantissa
UIA_BYTE = b
UIA_UINT16 = w
UIA_UINT16 = uw
Flag_e(F) = f
UIA_FLOAT = fp
UIA_INT8 = sb
