bus (the parallel bus is only available on the Q2687/X61 product).If an upgrade to the
Q2687/X61 is envisaged, and if the parallel bus is used, these pins will be mandatory for
parallel bus functionality.
With the OS 6.61: see “AT commands interface Guide” [7].
On the Q2687/X61 product, these pins are multiplexed with the control signals of the parallel
