UTMC Application Note_________________________________________
UT80CRH196KD Instruction Execution Times (in State Times)
Instructions are listed below by their hexadecimal opcode designator and corresponding mnemonic. The
instruction execution times are denoted by their state time equivalent (1 State Time = 2 * XTAL1 period).
• Single number state times denote Direct or Immediate address executions times.
• Dual number state times (SFR/MEM) indicate SFR as the execution time using SFRs and internal
memory, and MEM as the execution time using the memory controller.
• Indirect address modes list execution times as Normal:(SFR/MEM) / Auto-Increment: (SFR/MEM).
• Indexed address modes list execution times as Short:(SFR/MEM) / Long: (SFR/MEM).
Additionally, the effects of Program Status Flag settings are listed.

Opcode
Checkmark (√) indicates that a flag is set or cleared as appropriate.
Hyphen (-) indicates that the flag is not modified.
A one or zero, (1)(0) indicates that the flag will be in that state after the instruction.
An ‘s’ indicates that the instruction may set the flag if it is appropriate, but will not clear
the flag.
A ‘c’ indicates that the flag can be cleared but not set by the instruction.
A question mark (?) indicates that the flag will be left in an unknown state after the
operation.
