ducky64 42:06e6d21166a4 5 * TCIE probably isn't the optimal definition (since it waits for transmission
ducky64 42:06e6d21166a4 6 * complete before firing, as opposed to TXEIE which fires as soon as the buffer
ducky64 42:06e6d21166a4 7 * is empty and able to accept another frame to transmit), but this is what
ducky64 42:06e6d21166a4 8 * STM32F3's serial_api.c expects (and breaks if using TXEIE).
ducky64 42:06e6d21166a4 9 * But if serial_api.c changes to TXEIE this (probably) will also need to be
ducky64 42:06e6d21166a4 10 * updated.
