A simple 2 deep by 32 Byte Wide broadside FIFO is attached to ID = 08 to enable the firmware to efficiently pack fragments into aligned data words.
Device ID | Function | Description |
---|---|---|
08 | 64 Bytes XOUT 1 Byte to 32 Bytes, LSB justify XIN 32 Bytes. Note: FIFO has less than 32 Bytes, it will only return the valid data LSB justified | R2:R9 Data packed array |
08 | It will subtract 4 bytes from the current wr_ptr | R10[0] Control |
08 | It will reset the rd and wr ptrs | R10[1] Reset |
