Development Support
After receiving the eight security bytes from the host, the MCU transmits a break character signalling that
it is ready to receive a command.

Notes: 1 = Echo delay (2 bit times)
DD
The MCU does not transmit a break character until after the host sends the
eight security bytes.
2 = Data return delay (2 bit times)
4 = Wait 1 bit time before sending next byte.
