BIT7 OUT
× IN
Sets the direction of transfer of Endpoint 0.
Set the direction of transfer in data stage by interpreting the request in SETUP stage.
After completion of setting of the direction of the data stage, it can be executed by clearing the InForceNAK bit or
OutForceNAK bit to LOW in either of the EP0InControl or EP0OutControl register, which controls the direction of
data stage.
0: IN direction
1: OUT direction
BIT3-0 Max Packet Size
Sets MaxPacketSize of Endpoint 0.
The list corresponding to these bits is as follows:
After setting this field, AllFIFOClr in the EP0FIFOCtrl register must be set to HIGH once.
