Chapter 1 Overview
1.3.2 Address Registers (A0 and A1)
1.3.3 Frame Base Register (FB)
1.3.4 Program Counter (PC)
1.3.5 Interrupt Table Register (INTB)
1.3.6 User Stack Pointer (USP) and Interrupt Stack Pointer (ISP)
1.3.7 Static Base Register (SB)
1.3.8 Flag Register (FLG)
The address registers (A0 and A1) are 16-bit registers with functions similar to those of the data regis-
ters. These registers are used for address register-based indirect addressing and address register-
based relative addressing.
For some instructions, registers A1 and A0 can be combined to configure a 32-bit address register
(A1A0).
The frame base register (FB) is a 16-bit register used for FB-based relative addressing.
The program counter (PC) is a 20-bit register that indicates the address of the instruction to be executed
next.
The interrupt table register (INTB) is a 20-bit register that indicates the initial address of the interrupt
vector table.
There are two types of stack pointers: a user stack pointer (USP) and an interrupt stack pointer (ISP).
Each consists of 16 bits.
The stack pointer (USP/ISP) to be used can be switched with the stack pointer select flag (U flag).
The stack pointer select flag (U flag) is bit 7 of the flag register (FLG).
The static base register (SB) is a 16-bit register used for SB-based relative addressing.
The flag register (FLG) is an 11-bit register used as flags in one-bit units. For details on the functions of
the flags, see Section 1.4, “Flag Register (FLG).”
