SETIO Register, USB Endpoint 1~Endpoint 2 Set IN/OUT Pipe Register
Note: *USB definition: when host send a set Configuration , the Data pipe should send the DATA0 (about the Data
toggle) first. So, when Device received a set configuration setup command, user need to toggle this bit for
next data will send a Data0 first.
**Only need to set the data pipe as a input pile or output pile. The purpose of this function is to avoid the host
sent a abnormal IN or OUT token and make the endpoint disability.
