IMPLEMENTATION
Figure 1 depicts an application where four keys are connected to RB7:RB4. Internal pull-ups are used to maintain a high level on these inputs. In this example, LEDs are connected to RB3:RB0. When SW1 is pressed, LED1 is turned on and when SW2 is pressed, LED2 is turned on and so on. The PIC16CXXX is normally in SLEEP mode with the “change on state” interrupt enabled. When SW1 is pressed, ... |
