Register Pointer 0 (RP0) defines a moveable, 8-register section of the register space. The registers within
these spaces are called working registers. RP0 is used in addressing modes where the register operand is
expressed as a 4-bit address.
At reset, RP0 points to R192.

Register Pointer 1 (RP1) defines a moveable, 8-register section of the register space. The registers within
these spaces are called working registers. RP1 is used in addressing modes where the register operand is
expressed as a 4-bit address.
At reset, RP0 points to R200.

Stack operations are supported in the register file or in data memory. Bit 1 in the external Memory Timing
register (R254B0) selects between the two.
Register pair R216-R217 forms the Stack Pointer used for all stack operations. R216 is the MSB and
R217 is the LSB.
