Describe the bug
SAMD21 board don't high impedance TX pin when TX is disabled

This bug has been spotted by @XRobots .

Network configuration
More than 2 boards in a one-wire configuration (2 still work).

Additional context
When one of the board try to send something the 0 state is not 0 because the other board pulls it to 1. The more board you put on the network the more shitty your signal will be.
We have to switch TX in high impedance when it's disabled.
