Symbol Definitions
List of symbols used in flag changes
"flag" is a general term of lower 4-bit (VF, NF, CF, ZF) of PSW.
Execution cycle
Execution cycle may change depending on the status of the pipeline and the memory space to access.
Execution cycle described in this chapter is based on the following conditions;
The execution cycle considers the instruction fetch wait cycle and the data load /store wait cycle. the
instruction fetch wait cycle and the data load /store wait cycle depend on the resources to access.
Refer to [LSI manual] for details.
And, it may increase by the pipeline stall (instruction supply shortfall, register conflict, etc.).
Refer to [MN101L Series Instruction Manual] for details.
EX.1 BSET (abs8)bp Cycle: 2+2d
If the data access cycle is 1 (d = 0), then the execution cycle becomes 2 + 2 * 0 = 2 cycles.
If the data access cycle is 3 (d = 2), then the execution cycle becomes 2 + 2 * 2 = 6 cycles.
EX.2 JSR label Cycle: max(2+i, 4+2d)
If the instruction fetch cycle is 2 (i = 1) and the data access cycle is 1 (d = 0),
then the execution cycle becomes (2 + 1, 4 + 2 * 0) = 4 cycles.
