(a) When the A1SJHCPU(S8)/A1SHCPU is used
Even if the main program is stored in an E
capacities of the sampling trace, status latch, file register, and comment
areas cannot be increased, because the system uses the internal RAM
area (area indicated by *1 in the following figure) as in RAM operation.
