stmpe_set_altfunc()- set the alternate function for STMPE pins : Device to configure : Bitmask of pins to affect : block to enable alternate functions for
is assumed to have a bit set for each of the bits whose alternate function is to be changed, numbered according to the GPIOXY numbers.
If the GPIO module is not enabled, this function automatically enables it in order to perform the change.
