Register
General purpose registers
Registers R0 to R15 are general-purpose registers. The registers are used as the accumulator and memory
access pointers for CPU operations.
Of these 16 registers, the registers listed below are intended for special applications, for which some instructions
are enhanced.
R13 : Virtual accumulator
R14 : frame pointer
R15 : Stack pointer
The initial values of R0 to R14 after a reset are indeterminate. R15 is initialized to 0000 0000
H
(SSP value).
PS (Program Status)
This register holds the program status and is divided into the ILM, SCR, and CCR.
The undefined bits in the following illustration are all reserved bits. Reading these bits always returns “0”. Writing
to them has no effect.
