Description
Reset Handshake
These bits are used to confirm the communication
speed at which communication is being carried out
with the host controller (communication bit rate).
If the high-speed operation has been disabled (the
HSE bit in SYSCFG is cleared to 0), this module
establishes the full-speed operation without
executing the reset handshake protocol. If the high-
speed operation has been enabled (the HSE bit is
set to 1), this module executes the reset handshake
protocol (RHST = 01 during the execution) and feeds
back the execution results to these bits (11 for high-
speed operation, or 10 for full-speed operation).
00: Communication speed not decided
01: Reset handshake is being handled
10: Full-speed operation established
11: High-speed operation established
Note: If RHST is not established even though
sufficient waiting time has elapsed after USB
bus reset processing was complete (after
setting USBRST = 0), the USB cable may have
been disconnected during the USB bus reset
processing. In this case, USB bus status
should be checked with the LNST bits.
