analyzeBits: 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.

Value

An integer value respective to parameter ‘mode’.

Details

This routine analyses 16-bit integer values to get the indicators of MEDOKADS data
