Example 18: RTI Instruction
Problem: Calculate the number of 24-bit instruction program words and the number of
oscillator clock cycles required for the instruction
where
Solution: To determine the number of instruction program words and the number of
oscillator clock cycles required for the given instruction, the user should perform the fol-
lowing operations:
1. Look up the number of instruction program words and the number of oscillator clock
According to Table A-6, the RTI instruction will require one instruction program word and
will execute in (4+rx) oscillator clock cycles. The term “rx’’ represents the number of addi-
tional (if any) oscillator clock cycles required for an RTI or RTS instruction.
2. Evaluate the “rx’’ term using Table A-12.
According to Table A-12, the RTI instruction will require rx=(2
clock cycles. The term “ap’’ represents the number of additional (if any) oscillator clock
cycles that are required to access a P memory operand. Note that the term “(2 ap)” rep-
resents the two program memory instruction fetches executed at the end of an RTI or
RTS instruction to refill the instruction pipeline.

cycles required for the opcode-operand portion of the instruction in Table A-6.
