Bank Register [0xC002] [R/W]
Table 23. 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:
For example, if the Bank register is left at its default value of 0x0100, and R2 is read, then the physical address 0x0102 is read. Refer
to
Table 24. Bank Register Example
Address (Bits [15:4])
The Address field is used as a base address for all register addresses to start from.
Reserved
Write all reserved bits with ’0’.
Hardware Revision Register [0xC004] [R]
Table 25. Revision Register
Register Description
The Hardware Revision register is a read only register that indicates the silicon revision number. The first silicon revision is represented
by 0x0101. This number is increased by one for each new silicon revision.
Revision (Bits [15:0])
The Revision field contains the silicon revision number.
