; - The register field is H'FE80-H'FFFF; names below come from appendix B.
; - @aa:8 short absolute operands use BR as the upper address byte.
; - SCI baud inference uses section 14.2.8 BRR formulas when SMR/BRR are known.
; - LCD inference treats E-clock H'F200/H'F201 accesses as status/control and data candidates.
; - Pass --clock-hz to convert SCI BRR settings into numeric baud rates.
; - Cycle counts use Appendix A tables A-7/A-8 for on-chip access with no external wait states.
