ldsptl, ldspth (and ldtabh, ldtabl) about fppa-pdk-documentation HOT 5 CLOSED

I see you now added ldsptl and ldspth. Maybe it should be documented that these are undocumented?
Also I am wondering if there is also an instruction that loads from a to the stack?

Since all instructions are "undocumented" I see no difference here :-)

While the opcodes corresponding to the instructions are undocumented, there is still a difference: For ldsptl and ldspth, it is even undocumented, that they exist at all, while for the other instructions, the instructions and their behaviour are specified in the datasheets.

I created a test program and fully observed the behavior of LDSPTL/LDSPTH.

Documents been updated accordingly.

The documented ltabl and ltabh instructions from the 16-bit instruction set are still missing from the wiki.
