Speed Identification
USB V2.0 High Speed Global Interrupt
Endpoint Interrupts
The high speed reset is managed by the hardware.
At the connection, the host makes a reset which could be a classic reset (full speed) or a high
speed reset.
At the end of the reset process (full or high), the ENDRESET interrupt is generated.
Then the CPU should read the SPEED bit in UDPHS_INTSTAx to ascertain the speed mode of
the device.
Interrupts are defined in

Interrupts are enabled in UDPHS_IEN (see
and individually masked in UDPHS_EPTCTLENBx (see
