Universal Serial Bus Module (USB)
11.9.1.4 Transmit Endpoint 2
11.9.1.5 Receive Endpoint 2
11.9.2 Resume Interrupt
11.9.3 End-of-Packet Interrupt
Technical Data
206
For an IN transaction directed at endpoint 2, the USB module will
generate an interrupt by setting the TXD2F in the UIR1 register.
For an OUT transaction directed at endpoint 2, the USB module will
generate an interrupt by setting the RXD2F in the UIR1 register.
The USB module will generate a CPU interrupt if low-speed bus activity
is detected after entering the suspend state. A transition of the USB data
lines to the non-idle state (K state) while in the suspend mode will set the
RESUMF flag in the UIR1 register. There is no interrupt enable bit for this
interrupt source and an interrupt will be executed if the I-bit in the CCR
is cleared. A resume interrupt can only occur while the MCU is in the
suspend mode.
The USB module can generate a USB interrupt upon detection of an
end-of-packet signal for low-speed devices. Upon detection of an end-
of-packet signal, the USB module sets the EOPF bit and will generate a
CPU interrupt if the EOPIE bit in the UIR0 register is set.
