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) consist of 16 bits, and have the similar functions as 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) consists of 16 bits, and is used for FB-based relative addressing.
The program counter (PC) consists of 20 bits, indicating the address of an instruction to be executed
next.
The interrupt table register (INTB) consists of 20 bits, indicating the initial address of an interrupt vector
table.
There are two types of stack pointers: user stack pointer (USP) and interrupt stack pointer (ISP), each
consisting of 16 bits.
The stack pointer (USP/ISP) you want can be switched by a 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) consists of 16 bits, and is used for SB-based relative addressing.
The flag register (FLG) consists of 11 bits, and is used as a flag, one bit for one flag. For details about
the function of each flag, see Section 1.4, “Flag Register (FLG).”
