*1:
The number of device points can be changed at the parameters.
*2:
CPU uses V as an edge relay.
*3:
Instructions that used accumulators with the AnNCPU, AnACPU, and AnUCPU have different formats with the QCPU.
*4:
Can only be used by the $MOV instruction with the Q00JCPU, Q00CPU, and Q01CPU.
*5:
The Q00JCPU does not have file registers.
*6:
Applicable to products with the first 5 digits of the serial number 04122 or higher (Q00JCPU, Q00CPU, and QCPU).
*7:
