These special test modes are useful for system testing and debugging
To select these modes the RPC should be released from reset with the TXR line held low, normal RPC
operation will resume when the TXR is set high, i.e. TXR should be held while in these test modes.

reset pulse or 100ms after a power up.
There are 9 test modes which are selected by a binary code applied to the RPC's data bus. A 4 bit DIL
switch or rotary HEX switch connected between the data bus and 0V will select the modes (the RPC
has weak internal pull-up's). Alternatively the HOST may select the test modes by holding TXR low,
resetting the RPC and driving the required test mode code onto the data bus.

For normal operation of the RPC the TXR line must be held high for either 1ms
The RPC continuously monitors the mode selected i.e.. a reset is not required on mode changes.
