Write/Read "0"
When "1" is written into this bit, auto-response mode of
Set_Configuration request is set.
To the Set_Configuration request in auto-response mode,
transfer can be completed without occurring interrupt to CPU.
(Set of CCPL is not needed)

mode
and to the Set_Configuration request (ConfigurationValue is equal to 0)
in Configured state.
To the other state and to the Set_Configuration request which
ConfigurationVale is different from the value above, auto-response
is not done.
When "1" is written into this bit, automatic response mode of
Set_Address request is set.
To the Set_Address request in automatic response mode,
Set_Address transfer can be completed without occurring the interrupt to

Automatic response is done to the Set_Address request (DeviceAddress
is equal to 01h to 7Fh) which device state is Default state.
To the other state and to the Set_Address request which DeviceAddress
is not equal to 01h to 7Fh, automatic response is not done.
