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.

User can use PAGE instruction to change page to maintain program page by user. Otherwise, user can use
far jump (FJMP) or far call (FCALL) instructions to program user's code. And the program page is
maintained by EMC's complier. It will change user's program by inserting instructions within program.
Bit 4 : unused
Bit 5 ~ Bit 7 (P55 ~ P57) : 8-bit PORT5(5~7) I/O data register
User can use IOC register to define input or output each bit.
