Command Descriptions

Please consider these guidelines applicable to all the command descriptions that follow in this document.

  • Byte order. Wherever a parameter is specified as more than 1 byte in length, the order in which it must be sent/read is LSB first and MSB last.
  • Parameter for read commands: All read commands where a read parameter is not explicitly mentioned in the comand description, means those commands don't accept a read parameter. A Read parameter is defined only for certain read commands to specify the details of what is being sought to be read.
  • When the input parameter(s) to a command are in fixed point format, it is specified such as format = s8.2 or format = u12.4 etc. where s stands for signed and u stands for unsigned.

     Fixed-Point Representation:

    This representation has fixed number of bits for integer part and for fractional part. Negarive numbers are represented in two's complement format.

    Fixed Point representation - [Integer][Fraction]

    Example: Assuming the format is signed and using 32-bit format, with16 bits for the integer part and 16 bits for the fractional part. This will be refered to as s15.16 format.

    In this case, -43.625 and 43.625 are represented as follows:

    [1111111111010101][1010000000000000] = 0xFFD5A000 = -43.625

    [0000000000101011][1010000000000000] = 0x002BA000 = +43.625
