AUXDATAL – Auxiliary Data Low Byte
AUXDATAH – Auxiliary Data High Byte
• Bit 15:0 - DPTR[15:8]: Endpoint Data Pointer High Byte
This byte contains the 8 MSB of the Endpoint Data Pointer (DATAPTR).
The AUXDATAL and AUXDATAH registers represent the 16-bit value AUXDATA that is used for
multi-packet 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 bytes endpoints.
See
transfer.
• Bit 7:0 – AUXDATA[7:0]: Auxiliary Data Low Byte
This byte contains the 8 LSB of the Auxiliary Data. When multi-packet transfer is not used, this
SRAM location is free to use for other application data.
• Bit 7:0 – AUXDATA[15:8]: Auxiliary Data High Byte
This byte contains the 8 MSB of the Auxiliary Data. When multi-packet transfer is not used, this
SRAM location is free to use for other application data.
