PIPE FIFO Latency Control Register @0x368

This is register includes bits to control pipe FIFO latency

Table 1. i_pipe_fifo_latency_ctrl_reg
Bits SW Name Description Reset
0 R/W Disable PIPE TX FIFOCentering on Empty [DPTFCE] By default, if FIFO empty is reached, the PIPE TX FIFO accumulates two entries before reading the FIFO again. This is to prevent FIFO from reaching empty again. This bit must remain at 0 to allow the PIPE TX FIFO to recover effectively from a Empty condition. 0x0
1 R/W Reserved [DPRFLR] Reserved. Must be 1'b1 for functional mode. 0x1
14:2 R Reserved [R14] Reserved 0x0
15 R/W Disable PIPE TX FIFO Write Idle Filter [DPTFWF] This bit can be used to prevent PIPE_TX_FIFO from reaching full during TX Electrical Idle.
  • 0: During TX Electrical Idle, the PIPE_TX_FIFO is kept at half fill level by filtering the writes into the PIPE_TX_FIFO.
  • 1: The PIPE_TX_FIFO write filtering logic is turned off. Default value of this bit is 1.
0x1
31:16 R Reserved [R31] Reserved 0x0
