Use FSR register

Exercise 1 Figure I below shows an HCS12 microcontroller connected to a pushbutton switch (to Port A-bit 5) and to a 7-segment display (to Port B-bits from 6 to 0). Design an assembly program that increments the seven segment display every time the push button is pressed and then released. Assume that the initial value of the 7-segment is 0 and that the maximal value to be displayed is 9 5 VDC PB6 PB6 PAS PB4 PB2 PB1 PBO R= Figure 1 PIC18 You may need to use the Table below which shows the configuration of each segment of the 7- segment display for displaying number 0 to 9. Also assume that values 0x7E to 0x7B are stored in the PIC18's RAM memory at addressed 0x20 to Ox29. 030 058
