Important: The value of a reserved bit must be maintained in software. When you modify registers containing reserved bit fields, you must use a read-modify-write operation to preserve state and prevent indeterminate system behavior.

Halt TX. Writes will have no effect when FIFO_MODE == NONE, always readable. This register is use to halt transmissions for testing, so that the transmit FIFO can be filled by the master when FIFO's are implemented and enabled. Note, if FIFO's are implemented and not enabled the setting of the halt TX register will have no effect on operation. 0 = Halt TX disabled 1 = Halt TX enabled
