The variables entered in registers 1 to 74 are whole numbers read on 16 bits.
The variables entered in registers 1 to 29 are also accessible in “floating” format on 32 bits (registers 257 to 314 in the
“Float.” column of the table). The “floating” variables are read only.
Multiply each value in whole number format by the coefficient indicated in the “Coeff.” column of the table.

*:  Values valid since the last reset. Reset is carried out by writing a whole number value.
