Note :Some instructions of the 4501 Group has the skip function to unexecute the next described instruction. The 4501 Group just invalidates the next instruc-
tion when a skip is performed. The contents of program counter is not increased by 2. Accordingly, the number of cycles does not change even if skip
is not performed. However, the cycle count becomes “1” if the TABP p, RT, or RTS instruction is skipped.
INSTRUCTIONS
The 4501 Group has the 111 instructions. Each instruction is de-
scribed as follows;
(1) Index list of instruction function
(2) Machine instructions (index by alphabet)
(3) Machine instructions (index by function)
(4) Instruction code table
SYMBOL
The symbols shown below are used in the following list of instruc-
tion function and the machine instructions.
