Notes: x: 8-bit immediate data

m: 7-bit data memory address for HT48C10/HT48C30

addr: Program memory address

√: Flag(s) is affected

–: Flag(s) is not affected

*: Flag(s) may be affected by the execution status

(1): If a loading to PCL register occurs, the execution cycle of the instructions will be delayed

one more cycle (4 system clocks).

(2): If a skip to next instruction occurs, the execution cycle of instructions will be delayed one

more cycle (4 system clocks). Otherwise the original execution cycles remain unchanged.

(3) : (1) or (2)
