• Support as much as possible for future peripherals.
  
• Make the system not aware of multi-tap.
  
• Take measures against trouble.

• By specifying the required number of peripherals, the peripheral ID to be acquired and the peripheral size as input, each peripheral ID and peripheral data are acquired.
  Even if the
• peripheral acquisition ID is different from the connected peripheral ID, data is acquired if it is connected. For example, get analog device data as mouse data.

(Example)
Input
Required peripherals = 3
Peripheral ID = Digital device
Peripheral size = Digital device size

Connection status
Main unit connector 1 = Multi-tap 6P
Multi-tap connector 1 = Digital device
Multi-tap connector 3 = Analog device
Main unit connector 2 = Keyboard device
(Peripherals not connected other than above)

output

	Peripheral ID	Peripheral data
First	Digital	Digital format
Second	Not connected	Disable
3rd	Analog	Digital format
