MULTI-PURPOSE REGISTERS
The multi-purpose registers are CPU registers R0 to R15 which are used as accumulators for various compu-
tations and memory access pointers (fields that indicate the address) .
Special purposes are assumed for the following 3 of the 16 registers. Thus, some instructions are emphasized.
R13 : Virtual accumulator (AC)
R14 : Frame Pointer (FP)
R15 : Stack Pointer (SP)
Initial values for R0 to R14 on resetting are unspecified. The initial value of R15 will be 0000 0000
