The subroutine determines where to find them from the return address on the stack, and then reads the parameters it needs from program memory. Most instructions have a «destina- tion, source» field that specifies the data type, address- ing methods and operands involved. The MCS-151 family was also discontinued by Intel, but is widely available in binary compatible and partly enhanced variants. 8/16/32-bit binary compatible microcontroller: MCS-251 family This section needs expansion. The contents of the indicated variable is then copied into the in- ternal RAM location addressed by the stack pointer.
The 8048 and derivatives are still used today for basic model keyboards. That’s the end of the chapters, but there are two appen- dices. Set when addition produces a carry from bit 3 to bit 4. PSW.7: C Carry bit.
Opcode 04 specifies «INC A». 1y: DEC operand: Decrement the specified operand. During all other operations the B register is simply another location of the Special Function Register space. After completing the service routine, an RETI instruction returns the processor to the background program at the point from which it was in- terrupted. Instead, because the accumulator is a bit-addressible SFR, it is possible to branch on its most significant bit directly.
