The Z fields are reserved fields. They are required to be zero.
The FRAME NUMBER field specifies a frame number that must be used to
initialize the base register indicated by the REG ID value.
The REGISTER OFFSET field, present only if REGID
<=
1, specifies an offset
relative to the FRAME. This value is appropriate for the initialization of either the
IP register (REGID
=
0) or the SP register (REGID
=
1).
