Register Description
The Bank register maps registers
1.Shifting the four LSBs of the register address left by 1
2.ORing the four shifted bits of the register address with the 12 MSBs of the Bank Register
3.Forcing the LSB to zero
For example, if the Bank register is left at its default value of 0x0100, and R2 is read, then the physical address 0x0102 will be read. See Table 17 for details.
