Abstract
The 16 bit program counter of an 8 bit microprocessor within a camera is used to provide a 16 character display on the camera, such that messages with a 16 bit address are accessed. When the message for display is invoked, the address of the message is placed in the program counter, and a software interrupt is caused. Due to the software interrupt, the upper and lower bytes of the address in the program counter are pushed onto the stack, popped off the stack and stored in adjacent memory locations. The address may then be read from the adjacent memory locations, the message displayed and a return from interrupt effected.
