0110
Interrupt 1
Software is required to write this value for the host to read the
data associated with EP1interrupt endpoint from the
USBDRn registers.
0111
Interrupt 2
Software is required to write this value for the host to read the
data associated with EP2 interrupt endpoint from the
USBDRn registers.
1000
Suspend
The bus is in suspended mode, but the suspend interrupt
request has been cleared by previous reading of this register.
1001
Reset
The device has received a reset signal, but the reset interrupt
request has been cleared by previous reading of this register.
1010
Suspend interrupt pending
The bus is in suspended mode and the suspend interrupt is
pending. Current reading of this register clears the interrupt
request.
1011
Reset interrupt pending
The device has received a reset signal and the reset interrupt
is pending. Current reading of this register clears the interrupt
request.
1100
DADD falling
A falling edge was detected on DADD pin and the DADD
interrupt has been cleared by previous reading of this
register.
1101
DADD rising
A rising edge was detected on DADD pin and the DADD
interrupt has been cleared by previous reading of this
register.
1110
DADD falling interrupt pending
A falling edge has been detected on DADD pin and the DADD
interrupt is pending. Current reading of this register clears the
interrupt request.
1111
DADD rising interrupt pending
A rising edge has been detected on DADD pin and the DADD
interrupt is pending. Current reading of this register clears the
interrupt request.
