Description: 使用Usb cy7c68013与DSP通信，现在已经能够很正确的传递（上传数据）了。
USB资源：
使用了Ep２，Ep６
Ep2, out auto
Ep6, in auto
FlagA－－－ PF3
FlagB－－－ PF6
FlagC－－－ PF1
需要 EP２ EMPTY
EP6 FULL信号
因此
FlagA－－－ PF3 －－－ EP2空 －－－ ８ h
FlagB－－－ PF6 －－－ EP6满 －－－ e h
FlagC－－－ PF1
PINFLAGSAB＝0xE8
极性设置：
PKTEND，EPEF，EPFF high
其他的低
因此 FIFOPINPOLAR = 0x23
包结束信号接在DSP 的 PF７ 上面。
以上结束06.11.28
-Usb cy7c68013 with the use of DSP Communications, and now already in place to correct the transmission (upload data) a.
