# Documented sizes and base cycle counts for the instructions the 65C02 adds
# to the 6502, taken from the opcode list at
# http://6502.org/tutorials/65c02opcodes.html
#
# Checked against src/cpu/tables.h by tests/check_opcode_spec.py.
#
# ProcessorTests measures what the hardware does. This records what the
# documentation says, so a change to the tables that contradicts the published
# spec has to be argued for rather than slipped in. The two have disagreed
# once already, over the cycle count of $5C.
#
# The note is that page's footnote letter, marking counts that vary with
# decimal mode, a taken branch or a page crossing. The number here is the base.
