Posted on September 22, 2005 at 10:56In chapter 14.5 Register Description, page 278 there is a mistake on the register mapping:
The next paragraph
''All register addresses are expressed as offsets with respect to the USB Peripheral registers base address
0xC000 8000, except the buffer descriptor table locations, which starts at the address specified by the USB_BTABLE register. Due to the common limitation of APB bridges on word addressability, all register addresses are aligned to 32-bit word boundaries although they are 16-bit wide. The same address alignment is used to access packet buffer memory locations, which are located starting from
0xC000 8800. In this section, the following abbreviations are used:''
should be :

This is correct if we refer to the APB1 memory map page 17 (and correct compared to what I see when I debug)
