Subject: [usb] question in usb function core
hi everybody
"the assertion of se0 for more than 2.5us is interpreted as a reset by
device operating in low_speed or full_speed "in the page 40 of
2_0_Xcvr_Macrocell_1_05.pdf
is conflicted with "if idle asserted for >2.5us but <3.0 ms& FS mode,then
enter RESET"in the page 22 of USB FUNCTION CORE.
i think , se0 isnt same with idle in FS mode.
in programm USB IP FUNCTION
in module UTMI_IF
NORMAL:
begin
if (!mode_hs &T1_gt_2_5_us &T1_st_3_0_ms& !idle_long)
begin
me_cnt_clr=1'b1;
next_state=RESET;
end
the !idle_long in the NORMAL isnt same with in the page 22 of USB
FUNCTION CORE
