ROT
lower and higher word of the last value of RPM measured during the
measurement cycle; the value of the result is calculated according to
the formulas:
rps = 1/d – number of revolutions per second
rpm = 60/d – number of revolutions per minute
where:
d = m · 2
w
m = ((H & 7Fh)<<16) + ((L & 7FFFh)<<1)
w = ((H>>8) & 7Fh) – 87
L – lower word of the result
H – higher word of the result
& – bit product operator
