The Remote System asserts the programmer <START> signal to initiate the execution of a
‘Programming Project’.
The programmer will then assert the <ACTIVE> signal to indicate that it has commenced
programming.
At the end of the Programming operation the programmer asserts either the <OK> or <FAIL>
signal depending on the outcome.
The Remote System must then de-assert the <Start> signal to allow the programmer to reset
ready to program the next device.
