The following two variables are used to control HSNAK bit.

ep0_payload_remaining is set to the length field of of the Setup Data

structure (in SUDAV_ISR). At the begin of each payload data transfer (in

SUDAV_ISR, EP0IN_ISR and EP0OUT_ISR) the amount of payload of the current

transfer s calculated (<=64 bytes) and subtracted from

ep0_payload_remaining. For Vendor Commands HSNAK bit is cleared

automatically (at the end of EP0OUT_ISR) ifep0_payload_remaining == 0.

For Vendor Requests HSNAK bit is always cleared at the end of SUDAV_ISR.
