22.12.7
The endpoint base address and length registers define the location and size (start
address and length) of the endpoint specific buffers in the USB memory.
An EPLEN register is available for each of the 16 endpoints (n=0-15).
Reset value: 0XXXXXXX
Ln6 - Ln0
22.12.8
An ADROFF register is available for each of the 16 endpoints (n=0-15).
Reset value: 00
AO5 - AO0
As the USB memory size is 256 bytes per page, the maximum packet length is limited to
64 bytes. Therefore, only the lowest 6 bits of ADROFFn (AO5...AO0) are required for
offset definition. A write operation to ADROFFn is only successful if either
EPBSn.DIRn=0 and CBF=1 (USB write operation) or EPBSn.DIRn=1 and CBF=0 (USB
read operation).

Endpoint Buffer Length Register (EPLENn)
Address Offset Register (ADROFFn)
Endpoint n Buffer Length
The bits 0 to 6 of EPLENn define the length of the USB memory buffer for
endpoint n and can not be written if DINIT=1.
USB Address Offset
ADROFFn stores the 6-bit offset address for USB memory buffer
addressing by the C.
