TR0 to TR15 Considerations
TR bits are used only for retaining (OUT TR0 to TR15) and restoring (LD TR0 to TR15) the ON/OFF
status of branching points in programs with many output branches. They are thus different from general
bits, and cannot be used with AND or OR instructions, or with instructions that include NOT.
TR0 to TR15 output Duplication
A TR bit address cannot be repeated within
the same block in a program with many output
branches, as shown in the following diagram.
It can, however, be used again in a different
block.
