ST STM32F207 series User Manual

USB on-the-go high-speed (OTG_HS) RM0033
1168/1381 RM0033 Rev 9
OTG_HS all endpoints interrupt mask register (OTG_HS_DAINTMSK)
Address offset: 0x81C
Reset value: 0x0000 0000
The device endpoint interrupt mask register works with the device endpoint interrupt register
to interrupt the application when an event occurs on a device endpoint. However, the device
all endpoints interrupt (OTG_HS_DAINT) register bit corresponding to that interrupt is still
set.
OTG_HS device V
BUS
discharge time register (OTG_HS_DVBUSDIS)
Address offset: 0x0828
Reset value:
0x0000 17D7
This register specifies the V
BUS
discharge time after V
BUS
pulsing during SRP.
Bits 31:16 OEPINT: OUT endpoint interrupt bits
One bit per OUT endpoint:
Bit 16 for OUT endpoint 0, bit 31 for OUT endpoint 15
Bits 15:0 IEPINT: IN endpoint interrupt bits
One bit per IN endpoint:
Bit 0 for IN endpoint 0, bit 15 for endpoint 15
