Under development Preliminary document

Specifications in this document are tentative and subject to change.

2.2.1

General-Purpose Registers (R0 to R15)

This CPU has sixteen general-purpose registers (R0 to R15). R1 to R15 can be used as data registers or address registers.

R0, a general-purpose register, also functions as the stack pointer (SP). The stack pointer is switched to operate as the

interrupt stack pointer (ISP) or user stack pointer (USP) by the value of the stack pointer select bit (U) in the processor

status word (PSW).

2.2.2

Control Registers

This CPU has the following eight control registers.

 Interrupt stack pointer (ISP)

 User stack pointer (USP)

 Interrupt table register (INTB)

 Program counter (PC)

 Processor status word (PSW)

 Backup PC (BPC)

 Backup PSW (BPSW)

 Fast interrupt vector register (FINTV)
