Universal Serial Bus Module (USB)
9.9.1.2 Transmit Control Endpoint 0
Technical Data
160
For a control IN transaction directed at endpoint 0, the USB module will
generate an interrupt by setting the TXD0F flag in the UIR1 register. The
conditions necessary for the interrupt to occur are shown in the flowchart
in
