BIT Bit Name Action Value Function
Read - Always indicate 0.
15 - 12 reserved
Write - Always write in 0.
11 CPS soft reset Read/
Write -
PHY/LINK is reset by writing 0 after writing 1 (not automatic clear)
Note:
1) Perform read modify write so as not to re-write other bit.
2) Write 0 after 500 ns minimum passed after writing 1.
0 Not stop clock for providing to TSP I/F, CP I/F and data bridge.
10 clk off Read/
Write 1 Stop clock for providing to TSP I/F, CP I/F and data bridge when PMODE input
terminal is in H.
0 Deletes Self-ID packet in spite of receiving it during bus reset.
9 s-ID store
Note 1) Read/
Write 1 In case of receiving Self-ID packet during bus reset process, this bit stores 512 byte
at maximum accompanying with both Asynchronous receive FIFO and
Asynchronous transmit FIFO.
0 Enable CP-IC interface.(Needs external CP IC)
8 Cp_through Read/
Write 1 Disable CP-IC interface. CP-IC interface i s internally by passed.
0 TSSYNCA and TSSYNCB signals are neccesary to detect the first byte of the input
data to TSP interface.
7 Sync_in Read/
Write 1 TSSYNCA and TSSYNCB signals are not neccesary to detect the first byte of the
input data to TSP interface.
0 TSSYNCA and TSSYNCB signals are not asserted when the data is outputted from
TSP interface.
6 Sync_out Read/
Write 1
TSSYNCA and TSSYNCB signals are asserted when the data is outputted from TSP
interface.
Read 0 Always indicate 0.
5 reserved Write 0 Always write in 0.
0 Clears receive Isochronous-FIFO when bus reset occurred.
4 Iso-FIFO
no clr Read/
Write 1 Does not clear Isochronous-FIFO when bus reset occurred.
