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.
