Reserved bit - must be set to '0'.
XCVR Power Control. ‘1’ sets XCVR to low power. For normal operation set this bit to ‘0’.
Suspend mode is entered if bit 6 = ‘1’ and bit ‘0’ (USB Enable) = ‘0’.
Speed Select. ‘0’ selects full speed. ‘1’ selects low speed (also see
J-K1 and J-K0 force state control bits are used to generate various USB bus conditions.
Forcing K-state is used for Peripheral device remote wake-up, Resume, and other modes.
These two bits are set to zero on power up, see
DMA Transfer Direction. Set equal to ‘1’ for DMA READ cycles from SL811HS. Set equal to
‘0’ for DMA WRITE cycles.
Enable DMA operation when equal to ‘1’. Disable = ‘0’. DMA is initiated when DMA Count
High is written.
Overall Enable for Transfers. ‘1’ enables and’ ‘0 disables. Set this bit to ‘1’ to enable USB
communication. Default at power up = ‘0’
