Notes

• The pins will be polled at every TDMA frame interrupt, i.e. every 4.616ms. In SLEEP mode, the frequency of

polling is reduced, as polling will be done only when the module shortly suspends power saving when CTS is

activated. So in SLEEP mode polling intervals are extended to a range from 0.9s to 2.7s.

After a state change has been detected the "^SCPOL" URC is issued if the state of the pin remains stable for

8 TDMA frames (= 36.93ms) in Normal mode, or accordingly, 0.9s to 2.7s in SLEEP mode.

• If the <value> of one or more of the polled pins has changed since polling has been performed last time, or

since a particular pin or its entire port have last been queried with AT^SGIO, polling will be suspended to send

a URC. There will be one URC reported for each polled pin whose <value> has changed, and one for each

polled port with one or more changed pins.
