• WAKE_UP: Wake Up CPU Interrupt
0 = cleared by setting the WAKE_UP bit in UDPHS_CLRINT.
1 = set by hardware when the UDPHS controller is in SUSPEND state and is re-activated by a filtered non-idle signal from
the UDPHS line (not by an upstream resume). This triggers a UDPHS interrupt when the WAKE_UP bit is set in
UDPHS_IEN register. When receiving this interrupt, the user has to enable the device controller clock prior to operation.
Note: this interrupt is generated even if the device controller clock is disabled.
• ENDOFRSM: End Of Resume Interrupt
0 = cleared by setting the ENDOFRSM bit in UDPHS_CLRINT.
1 = set by hardware when the UDPHS controller detects a good end of resume signal initiated by the host. This triggers a
UDPHS interrupt when the ENDOFRSM bit is set in UDPHS_IEN.
• UPSTR_RES: Upstream Resume Interrupt
0 = cleared by setting the UPSTR_RES bit in UDPHS_CLRINT.
1 = set by hardware when the UDPHS controller is sending a resume signal called “upstream resume”. This triggers a
UDPHS interrupt when the UPSTR_RES bit is set in UDPHS_IEN.
• EPT_x: Endpoint x Interrupt
0 = reset when the UDPHS_EPTSTAx interrupt source is cleared.
1 = set by hardware when an interrupt is triggered by the UDPHS_EPTSTAx register and this endpoint interrupt is enabled
by the EPT_INT_x bit in UDPHS_IEN.
• DMA_INT_x: DMA Channel x Interrupt
0 = reset when the UDPHS_DMASTATUSx interrupt source is cleared.
1 = set by hardware when an interrupt is triggered by the DMA Channelx and this endpoint interrupt is enabled by the
DMA_INT_x bit in UDPHS_IEN.
