[Detect of command execution status]
When control type is "H0001" or "H0003" and you add the below two circuits just after FUN201 command
circuit, you can detect of command execution status.

Caution:
- During execution of command, when system area(s+1, s+2) of s parameter is changed, execution of
FUN201 command is not guaranteed.
- After execute flag set 1, FUN201 command is started to execute maximum 1 scan later.
- When execute flag is 0 and FUN201 is executed, read/write to the applied area is not execute.
