Chapter 1 Overview
(2) SB/FB Relative Bit Specification
For SB/FB-based relative addressing, use bit 0 of the address that is the sum of the address set in
static base register (SB) or frame base register (FB) plus the address set in base as the reference
(= 0), and set the desired bit position in bit.
(3) Address Register Indirect/Relative Bit Specification
For address register-based indirect addressing, use bit 0 of address 00000
and set the desired bit position in the address register (An).
For address register-based relative addressing, use bit 0 of the address set in base as the reference
(= 0) and set the desired bit position in the address register (An).
