Data Sheet
Figure 22-20 USB Configuration Block
The six byte USB configuration block must be transfered sequentially (byte 0 to byte 5)
from the CPU to the USB module for each endpoint (i.e. always for 16 endpoints)
beginning with endpoint 0, followed by the USB configuration block for endpoint 1 and
so on up to the USB configuration block for endpoint 15. EPNum is set for endpoints 0
up to15. After this action, bit DINIT is reset by hardware, and the software reset and
initialization sequence are finished.
Note: A software reset initiated by setting bit DCR.SWR to ’1’, which should be done at
the earliest 4 clock cycles after DCR.UCLK has been set to ’1’, resets also bit
UCLK . This means that UCLK has to be set to ’1’ again. This reinforcement of
DCR.UCLK has to be programmed earliest 20 clock cycles after SWR has been
set to ’1’.
