n
is any integer from 2 to 25.
When
f

is > 25.65 kS/s,
f

where
n
is any integer from 2 to 3.
However, the data rate m

st remain within the appropriate data rate
range. Refer to the

abo
u
t the data rate range. When
u
sing the internal master timebase
of 12.8 MHz, the res

lt is data rates of 50 kS/s, 33.33 kS/s, 25 kS/s,
and so on down to 2.0 kS/s, depending on the val
u
e of
n
. When
u
sing an external timebase with a freq
