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,
transfer can be completed without occurring the interrupt to
CPU. (Set of CCPL is not needed)
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.
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)
Auto-response is done to the Set_Configuration request
(ConfigurationValue is not equal to 0) in Address device state
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.

If this bit is "1", every time when read EP0_FIFO register,the value of
ODLN register is counted down.
Read count mode
If this bit is set to "1", data register of FIFO turns to 8-bit mode and
lower 8 bit[7:0] becomes enable when access the "FIFO Data Register"
of endpoint.
When transmit data of odd number byte, data must be written in 8-bit
mode.
When read in 8-bit mode, set to 8-bit mode before data receive.
