LPCUSB, USBCDC; A reply to thread-16477

A reply to thread-16477

http://www.keil.com/forum/docs/thread16477.asp

I tried to post something on thread-16477, but somehow failed, and lost my original writing. After that, it seems thread-16477 has been touched, and updated with nothing.

    Found another thing in the LPCUSB Library:

    /* USB Controller */
#define USB_BASE_ADDR      0xFFE0C000

/* USBPortSel only available on the LPC2378 */
#define USBPortSel         (*(volatile unsigned int *)(USB_BASE_ADDR + 0x110))

/* USB Clock Control Registers */
#define USBClkCtrl         (*(volatile unsigned int *)(USB_BASE_ADDR + 0xFF4))
#define USBClkSt           (*(volatile unsigned int *)(USB_BASE_ADDR + 0xFF8))

/* USB Device Interrupt Registers */
#define USBIntSt           (*(volatile unsigned int *)(USB_BASE_ADDR + 0x1C0))
#define USBDevIntSt        (*(volatile unsigned int *)(USB_BASE_ADDR + 0x200))

    The Address of USB Device Interrupt Registers (USBIntSt) is incorrect.

    But it seems that LPCUSB does not use this Register actually.

    The above Wiki of LPCUSB has been emptied. Don't know how to contact the maintainers of LPCUSB.
