Subject: [usb] about the syn packet
Hi everyone,
While i am reading the code usb_tx_phy.v in the PHY1.1 core, i
find that everytime when the controller want to send packet to the
host. It active the ld_sop_d signal and then write all zero to
hold_reg
then it will send out all zero before sending the real data.
I would like to know why write "00000000" rather than
writing "00000001" to the hold_reg, as the synchronized packet in usb
should be "00000001".
Thx for your help
