Macros
Keypad scan index configuration
Choose the scan index for each scan column in the [0,7] range. Warning : caution should be taken in the choice of this index regarding the board schematics. For instance, on EVK1100, if scan[4] & scan[5] were chosen, LED5 will blink at the keypad scan rate because LED5 and scan[4] and scan[5] are using the same pins(PB19 & PB20).
