Details:
In the attached files, you'll see the line inside the main() while() loop
with the instruction:
//Clear service variable
service = 0;
service is defined as a volatile uint8_t. When I run the JTAG mkII emulator,
the assembly code for this line is:
STS 0x0100,R1
0x0100 is the address where the value of service is stored. However, R1 is
always 0x01, not 0x00.
