3.16.3.24 EPx_MODE Register (x: 1 to 3)
This register sets transfer mode of endpoint (EP1 to EP3).
If transaction of SET_CONFIG and SET_INTERFACE are set to software control,
this control must use appointed config or interface. When it is setting mode, access
this register.

There is limitation to timing that can be written.
If transaction for SET_CONFIG and SET_INTERFACE are set to software control,
after received INT_SETUP interrupt, finish writing before access EOP register. This
register prohibits writing when it is other timing, and it is ignored.
DIRECTION (Bit0)
0: OUT Direction of from host to device
1: IN Direction of from device to host
MODE [1:0] (Bit2 and bit1)
00: Control transfer type
01: Isochronous transfer type
10: Bulk transfer type or interrupt transfer type
11: Interrupt (No toggle)
Note: If setting endpoint that is set to Isochronous transfer mode to “no use”, after changed to
Isochronous mode, set to “no use” by COMMAND register.
PAYLOAD [2:0] (Bit3, bit4 and bit5)

Note1: Max packet size of Isochronous transfer type is 1023 bytes.
Note2: If except 8, 16, ..., 1023 was set to wMaxPacketSize of descriptor, Payload
more than descriptor value is set by auto-answer of Set_Configration and
Set_Interface.
