AT43USB326
3313D–USB–04/06
Hub Endpoint 0 Byte Count Register – HBYTE_CNT0
Function Endpoint 0..2 Byte Count Register – FBYTE_CNT0..2
The contents of these registers stores the number of bytes to be sent or that was received by
USB Hub and Function endpoints. This count includes the 16-bit CRC. To get the actual byte
count of the data, subtract the count in the register by 2. The maximum byte count supported
by the AT43USB326 is 8 bytes. Hub endpoint 1 has no byte count register.
Bit 7..6 – Reserved
These bits are reserved in the AT43USB326 and will read as zero.
