Description :
The function bit test, combines through AND the corresponding bits of the variable Data with the bit of the variable maschera and load the Boolean result in the variable Q. Where the variable maschera is: maschera = 2 Bit
If the variable Bit is lower than zero (0) or greater than thirty-one (31) the TSTB from Q equal to zero (0). Error conditions that sets ENO = 0: none.
