Figure 12-40. SETUP Data Buffer
This buffer contains the 8 bytes of SETUP packet data from the most recently received
CONTROL transfer.
The data in SETUPBUF is valid when the SUDAVIR (Setup Data Available Interrupt
Request) bit is set. The 8051 responds to the SUDAV interrupt by reading the SETUP
bytes from this buffer.
