1.5 Register Banks
Chapter 1 Overview
The R8C/Tiny has two register banks, each comprising data registers (R0, R1, R2, and R3), address regis-
ters (A0 and A1), and a frame base register (FB). These two register banks are switched by the register
bank select flag (B flag) in the flag register (FLG).
Figure 1.5.1 shows the configuration of the register banks.
