Register File
This device features 1056 bytes of register file space, organized in 256 byte banks. Bank 0
contains 237 bytes of RAM addressed as general-purpose registers, 4 port addresses (of
which one is reserved), and 16 control register addresses. Banks 1, 2, and 3 each contain
256 general-purpose register bytes. Banks D and F each contain 16 addresses for control
registers. All other banks are reserved and must not be selected.
The current bank is selected for 8-bit direct or indirect addressing by writing Register
Pointer bits RP[3:0]. In the current bank, a 16-byte working register group (addressed as
R0–R15) is selected by writing RP[7:4]. A working register operand requires only 4 bits
of program memory. There are 16 working register groups per bank. See
