2.7.1
Interrupt masks
The VBSE, RSME, SOFE, DVSE, CTRE, BEMPE, NRDYE, and BRDYE bits of the INTENB0 register and BCHGE,
DTCHE,
SIGNE, SACKE
of INTENB1 register operate as interrupt mask bits. Each of the bits should be used
to specify whether interrupt signal output is enabled or disabled for the INT_N pin.
The BRDYENB register, NRDYENB register and BEMPENB register operate as the BRDY interrupt mask bit,
the NRDY interrupt mask bit, and the BEMP interrupt mask bit, respectively, for the each corresponding pipe.
2.7.2
Device state transition interrupts
The URST, SADR, SCFG, and SUSP bits of the INTENB0 register operate as interrupt mask bits for the device
state transition interrupt (DVST). If a factor is disabled, no device state transition interrupt is issued in
response to the pertinent factor. However, the device state (DVSQ) transits in keeping with the circumstances.
This function is effective only at the time of a peripheral mode.
2.7.3
Control transfer stage transition interrupts
The WDST, RDST, CMPL and SERR bits of the INTENB0 register should be used to set the interrupt factors
for the control transfer stage transition interrupt (CTRT). If a factor is disabled, no control transfer stage
transition interrupts are issued in response to the pertinent factor.
This function is effective only at the time of a peripheral mode.
2.7.4
USB bus change interrupt
Interruption can be generated when a USB bus state changes. This interruption enable with the BCHGE bit of
INTENB1
register. This interruption is used for the peripheral connection and detection of a remote wakeup
signal in the Host mode. Please do not enable interruption during communication (at the time of "UACT=1"
setup). The bus change interruption is generated whichever it has chosen of Host and Peripheral mode.
2.7.5
Full-Speed detach detect interrupt
When Host mode, interruption can be generated when peripheral device is detached at the time of Full-Speed
mode. This interruption enable with the DTCHE bit of INTENB1 register.
2.7.6
Setup transaction error detect interupt
Interruption can be generated when the ACK packet from peripheral device isn’t able to be received at the
time of sending setup transaction at Host mode. This interruption enable with the SIGN bit of INTENB1 register.
2.7.7
Setup transaction complete interrupt
Interruption can be generated when the ACK packet from peripheral device is received at the time of sending
setup transaction at Host mode. This interruption enable with the SACKE bit of INTENB1 register.
2.7.8
Operations in the low-power sleep state
The VBSE, RSME, BCHG interrupts are generated in the low-power sleep state as well..
