■ GENERAL-PURPOSE REGISTERS
R0 to R15 are general-purpose registers embedded on the CPU. These registers functions as an accumulator
and a memory access pointer.
Of the above 16 registers, following registers have special functions. To support the special functions, part of
the instruction set has been sophisticated to have enhanced functions.
R13: Virtual accumulator (AC)
R14: Frame pointer (FP)
R15: Stack pointer (SP)
Upon reset, values in R0 to R14 are not fixed. Value in R15 is initialized to be 0000 0000H (SSP value).
