1.5 Register Bank
Chapter 1 Overview
The M16C has two register banks, each configured with data registers (R0, R1, R2, and R3), address
registers (A0 and A1), and frame base register (FB). These two register banks are switched over by the
register bank select flag (B flag) of the flag register (FLG).
Figure 1.5.1 shows a configuration of register banks.
