Data Sheet
22.12.9
An USBVAL register is available for each of the 16 endpoints (n=0-15).
Reset value: 00
USBVALn.7
-USBVALn.0
The data transfers between USB memory and the µC are handled via the SFR
USBVALn. With a µC write access to USBVALn, the value written into it is transferred to
the USB memory location defined by the content of the endpoint specific base address
register EPBAn and the address offset register ADROFFn. During USB memory read
accesses by the µC, data is written in the reverse direction. Access to USBVALn is only
successful if either EPBSn.DIRn=0 and CBF=1 (USB write operation) or EPBSn.DIRn=1
and CBF=0 (USB read operation).

USB Data Value
USBVALn stores the 8-bit data byte during transfers from µC to USB
memory and from USB memory to the µC. Bit NOD in the EPIRn register
indicates when the µC processes a USBVALn read operation with an
empty USB buffer or a USBVALn write operation to a full USB buffer.
