Hub End-point 0 Byte Count Register – HBYTE_CNT0
Function End-point 0..3 Byte Count Register – FBYTE_CNT0..3
The contents of these registers stores the number of bytes to be sent or that was received by
USB Hub and Function end-points. 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 hub EP0 and function EP3 have
8 byte FIFOs while function EP1 and EP2 have 64 byte FIFOs. Hub end-point 1 has no byte
count register.
• Bit 7..6 – Reserved
These bits are reserved in the AT43USB355 and will read as zero.
• Bit 5..0 – BYTCT5..0: Byte Count – Length of End-point Data Packet
Function EP0 $1FCD
Function EP1 $1FCC
Function EP2 $1FCB
Function EP3 $1FCA
Hub EP0 $1FCF
