AT43USB351M
3302E–USB–7/04
Function Endpoint 0..4 Data Register – FDR0..4
These registers are used to read data from or to write data to the Function Endpoint 0 FIFOs.
Bit 7..0 – FDAT7..0: FIFO Data
Function Endpoint 0..4 Byte Count Register – FBYTE_CNT0..4
The contents of these registers stores the number of bytes to be sent or that was received by
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 functions EP3 and EP4 have 8-byte FIFOs
while function EP1 and EP2 have 64-byte FIFOs.
Bit 7 – Reserved
This bit is reserved in the AT43USB351M and will read as zero.
Bit 6..0 – BYTCT6..0: Byte Count – Length of Endpoint Data Packet
