Bit Analysis
Description
Analyses bits of a 16-bit integer
Usage
analyzeBits(value, mode=1, bitpos=0)Arguments
value |
A 16-bit integer value |
mode |
If mode is 0, the algorithm returns the bit on position ‘bitpos’. If mode is 1 (default), the algorithm returns the most significant bit, if mode is 2 it returns the second significant bit and if mode is 3 the return value is the integer value of the last four bits |
bitpos |
An integer value between 0 and 15 determining the position of the bit to read when mode is 0. |
Details
This routine analyses 16-bit integer values to get the indicators of MEDOKADS data
Value
An integer value respective to parameter ‘mode’.
