... DPLUS/DMINUS Impedance Termina- has CC tion The CY7C68000 does not require external resistors for USB data line impedance termination or an external pull up resistor on the DPLUS line. These resistors are incorporated into the part. They are factory trimmed to meet the requirements of USB 2.0. Incorporating these resistors also reduces the pin count on the part ...

... TX Holding Register on the rising edge of CLK. If TXValid is TRUE and TXReady is asserted at the rising edge of CLK, the CY7C68000 will load the data on the data bus into the TX Holding Register on the next rising edge of CLK. At that time, the SIE should immedi- ately present the data for the next transfer on the data bus Receive Data Valid ...
