This register sets the answer for Class Request either automatically in hardware or
by control through software. Each bit represents a kind of request.
When relevant bit in this register is set to "0", the answer is executed automatically
by hardware. When relevant bit in this register is set to "1", the answer is controlled
by software. If a request is received during hardware control, the interrupt signal
(INT_SETUP, INT_ENDPOINT0, INT_STATUS, INT_STATUSNAK) is set to disable.
If a request is received during software control, the interrupt signal is asserted, and it
is controlled by software.
