The AVR Stack Pointer is implemented as two 8-bit registers SPL and SPH in the I/O
space. The number of bits actually used is implementation dependent. Note that the
data space in some implementations of the AVR architecture is so small that only SPL
is needed. In this case, the SPH Register will not be present.

For ELPM/SPM instructions, the Z-pointer is a concatenation of RAMPZ, ZH, and ZL.
Note that LPM is not affected by the RAMPZ setting.
Bit 7:2 – Res5:0 - Reserved
For compatibility with future devices, be sure to write these bits to zero.
Bit 1:0 – RAMPZ1:0 - Extended Z-Pointer Value
These two bits represent the MSB's of the Z-Pointer.

Description
RAMPZ1:0
0
Default value of Z-pointer MSB's.
For ELPM/SPM instructions, the Z-pointer is a concatenation of RAMPZ, ZH, and ZL,
as shown in Figure 7-3 below. Note that LPM is not affected by the RAMPZ setting.

The actual number of bits is implementation dependent. Unused bits in an
implementation will always read as zero. For compatibility with future devices, be sure
to write these bits to zero.
