AUXDATAL – Auxiliary Data Low
AUXDATAH – Auxiliary Data High
• Bit 15:0 - DPTR[15:8]: Endpoint Data Pointer High
This byte contains the eight msbs of the endpoint data pointer (DATAPTR).
The AUXDATAL and AUXDATAH registers represent the 16-bit value, AUXDATA, that is used
for multipacket transfers.
For IN endpoints, AUXDATA holds the total number of bytes sent. AUXDATA should be written
to zero when setting up a new transfer. For OUT endpoints, AUXDATA holds the total data size
for the complete transfer. This value must be a multiple of the maximum packet size, except for
ISO 1023-byte endpoints.

transfers.
• Bit 7:0 – AUXDATA[7:0]: Auxiliary Data Low
This byte contains the eight lsbs of the auxiliary data (AUXDATA). When multipacket transfer is
not used, this SRAM location is free to use for other application data.
• Bit 7:0 – AUXDATA[15:8]: Auxiliary Data High
This byte contains the eight msbs of the auxiliary data (AUXDATA). When multipacket transfer is
not used, this SRAM location is free to use for other application data.
