/* Get single integer or byte from shared or data memory
* Takes integer index argument, returns Number at that index
* Careful: index for int and byte will differ! index for int == index for byte / 4 (simplified)
* Legacy considerations: execute() above takes the PRU num as the first argument, but since
* previously getDataRAMInt defaulted to PRU num 1 we don't want to break programs. Therefore,
* the PRU num stays optional and defaults to 0.
