Bit 0 ~ Bit 5 (RSR0 ~ RSR5) : Indirect addressing for common registers R20 ~ R3F
RSR bits are used to select up to 32 registers (R20 to R3F) in the indirect addressing mode.
Bit 6 ~ Bit 7 (RB0 ~ RB1) : Bank selection bits for common registers R20 ~ R3F
These selection bits are used to determine which bank is activated among the 4 banks for 32 register (R20 to
R3F)..
Please refer to VII.1 Operational registers for details.
