Access Type:
• SPEED: Speed Status
0 = reset by hardware when the hardware is in Full Speed mode.
1 = set by hardware when the hardware is in High Speed mode
• DET_SUSPD: Suspend Interrupt
0 = cleared by setting the DET_SUSPD bit in UDPHS_CLRINT register
1 = set by hardware when a UDPHS Suspend (Idle bus for three frame periods, a J state for 3 ms) is detected. This triggers
a UDPHS interrupt when the DET_SUSPD bit is set in UDPHS_IEN register.
• MICRO_SOF: Micro Start Of Frame Interrupt
0 = cleared by setting the MICRO_SOF bit in UDPHS_CLRINT register.
1 = set by hardware when an UDPHS micro start of frame PID (SOF) has been detected (every 125 us) or synthesized by
the macro. This triggers a UDPHS interrupt when the MICRO_SOF bit is set in UDPHS_IEN. In case of detected SOF, the
MICRO_FRAME_NUM field in UDPHS_FNUM register is incremented and the FRAME_NUMBER field doesn’t change.
Note:
• INT_SOF: Start Of Frame Interrupt
0 = cleared by setting the INT_SOF bit in UDPHS_CLRINT.
1 = set by hardware when an UDPHS Start Of Frame PID (SOF) has been detected (every 1 ms) or synthesized by the
macro. This triggers a UDPHS interrupt when the INT_SOF bit is set in UDPHS_IEN register. In case of detected SOF, in
High Speed mode, the MICRO_FRAME_NUMBER field is cleared in UDPHS_FNUM register and the FRAME_NUMBER
field is updated.
• ENDRESET: End Of Reset Interrupt
0 = cleared by setting the ENDRESET bit in UDPHS_CLRINT.
1 = set by hardware when an End Of Reset has been detected by the UDPHS controller. This triggers a UDPHS interrupt
when the ENDRESET bit is set in UDPHS_IEN.
