Stellaris^® LM4F232H5QC Microcontroller
Register 5: USB Transmit Interrupt Enable (USBTXIE), offset 0x006
USBTXIE is a 16-bit register that provides interrupt enable bits for the interrupts in the USBTXIS
OTG A / _{register. When a bit is set, the USB interrupt is asserted to the interrupt controller when the}
Host
corresponding interrupt bit in the USBTXIS register is set. When a bit is cleared, the interrupt in the
USBTXIS register is still set but the USB interrupt to the interrupt controller is not asserted. On reset,
all interrupts are enabled.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
TX Endpoint 7 Interrupt Enable
Value Description
1 An interrupt is sent to the interrupt controller when the EP7 bit
in the USBTXIS register is set.
