6.0
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 acces-
sible through the register space by the user.
Table 6-1. CPU Registers and Register Names
The 16-bit Program Counter Register (CPU_PC) allows for
direct addressing of the full eight Kbytes of program memory
space.

The Accumulator Register (CPU_A) is the general-purpose
register that 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-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 can also be 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] is used to globally enable or disable
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 (i.e., AND,
OR, XOR). See Table 8-1.
