Registers
General-purpose register
Registers R0 to R15 are general-purpose registers. These registers can be used as accumulators for computation
operations and as pointers for memory access.
Enhanced commands are provided for some of the 16 registers to enable their use for particular applications.
R13 : Virtual accumulator
R14 : Frame pointer
R15 : Stack pointer
Initial values at reset are undefined for R0 to R14. The value for R15 is 00000000H (SSP value).
PS (Program Status)
This register holds the program status, and is divided into three parts, ILM, SCR, and CCR.
All undefined bits (-) in the diagram are reserved bits. The values are always read "0". Write access to these
bits is invalid.
