Pulse rate: max. 1000 pulses per
second
Recommendation: Connect
pull-up or pull-down resistors to
all GPIO lines intended for use
as output. See also
If lines are unused (not config-
ured) keep lines open.
Alternatively, the GPIO10 line
can be configured as a pulse
counter for pulse rates from 0 to
1000 pulses per second.

for details.
Unused input lines should be
tied to GND via pull down resis-
tors. In addition, DAI1 requires
a 47kOhm pull down resistor to
be placed as close as possible
to the module. Unused output
lines must be left open.
