6. CPU Architecture
This family of microcontrollers is based on a high performance,
8-bit, Harvard architecture microprocessor. Five registers control
the primary operation of the CPU core. These registers are
affected by various instructions, but are not directly accessible
through the register space by the user.
Table 6-1. CPU Registers and Register Names
The 16-bit Program Counter Register (CPU_PC) allows direct
addressing of the full 8 Kbytes of program memory space.
The Accumulator Register (CPU_A) is the general purpose
register, which holds the results of instructions that specify any
of the source addressing modes.
The Index Register (CPU_X) holds an offset value that is used
in the indexed addressing modes. Typically, this is used to
address a block of data within the data memory space.

The Stack Pointer Register (CPU_SP) holds the address of the
current top of the stack in the data memory space. It is affected
by the PUSH, POP, LCALL, CALL, RETI, and RET instructions,
which manage the software stack. It is also affected by the SWAP
and ADD instructions.
The Flag Register (CPU_F) has three status bits: Zero Flag bit
[1]; Carry Flag bit [2]; Supervisory State bit [3]. The Global
Interrupt Enable bit [0] globally enables or disables interrupts.
The user cannot manipulate the Supervisory State status bit [3].
The flags are affected by arithmetic, logic, and shift operations.
The manner in which each flag is changed is dependent upon
the instruction being executed, such as AND, OR, XOR, and
others. See
