() Fixed an issue where STOP would be sent twice when a read message
is only 1 byte.
() Skip resetting the controller when NACK is received. This is not
an issue with the controller, so there is no need to reset
the controller and its state machine.
() Cosmetic changes to trim lines > 80 characters.
