■ GENERAL-PURPOSE REGISTERS
General-purpose registers are CPU registers R0 through R15 and used as accumulators during various oper-
ations and as memory access pointers (fields indicating addresses) .
Of the 16 general-purpose registers, the following registers are assumed for specific applications. For this reason,
some instructions are enhanced.
R13 : Virtual accumulator (AC)
R14 : Frame pointer (FP)
R15 : Stack pointer (SP)
Initial values to which R0 through R14 are reset are not defined. The initial value of R15 is 0000 0000H (the SSP
value) .
