Description
Reserved
The value read from these bits is always 0. Do not set these bits.
Wake Up CPU Interrupt
This bit is set by hardware when the USB controller is in SUSPEND state and is re-
activated by a non-idle signal FROM USB line (not by an upstream resume). This
triggers a USB interrupt when EWUPCPU is set in Figure 21-5 on page 141.
When receiving this interrupt, user has to enable all USB clock inputs.
This bit will be cleared by software (USB clocks must be enabled before).
End Of Reset Interrupt
This bit is set by hardware when a End Of Reset has been detected by the USB
controller. This triggers a USB interrupt when EEORINT is set (see
141).
This bit will be cleared by software.
Start of Frame Interrupt
This bit is set by hardware when an USB Start of Frame PID (SOF) has been detected.
This triggers a USB interrupt when ESOFINT is set (see
This bit will be cleared by software.
Reserved
The value read from this bit is always 0. Do not set this bit.
Reserved
The value read from this bit is always 0. Do not set this bit.
Suspend Interrupt
This bit is set by hardware when a USB Suspend (Idle bus for three frame periods: a J
state for 3 ms) is detected. This triggers a USB interrupt when ESPINT is set in see
Table 21-5 on page
This bit will be cleared by software BEFORE any other USB operation to re-activate the
macro.
