Bank Register [0xC002] [R/W]
Figure 8. Bank Register
Register Description
The Bank register maps registers R0–R15 into RAM. The
eleven MSBs of this register are used as a base address for
registers R0–R15. A register address is automatically
generated by:
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.
