9.9.1.3 Transmit Endpoint 1
MC68HC908JB8•MC68HC08JB8•MC68HC08JT8 — Rev. 2.3
Freescale Semiconductor
For an IN transaction directed at endpoint 1, the USB module will
generate an interrupt by setting the TXD1F in the UIR1 register. The
conditions necessary for the interrupt to occur are shown in
Figure
