These special test modes are useful for system testing and debugging
To select these modes the RPC2A should be released from reset with the TXR line held low, normal
RPC2A operation will resume when the TXR is set high, i.e. TXR should be held while in these test
modes.
note:
reset pulse or 100ms after a power up.
There are 9 test modes which are selected by a binary code applied to the RPC2A's data bus. A 4 bit DIL
switch or rotary HEX switch connected between the data bus and 0V will select the modes (the RPC2A
has weak internal pull-up's). Alternatively the HOST may select the test modes by holding TXR low,
resetting the RPC2A and driving the required test mode code onto the data bus.

For normal operation of the RPC2A the TXR line must be held high for either 1ms
The RPC2A continuously monitors the mode selected i.e.. a reset is not required on mode
