Notes on Test Mode Register Bits:
1. Writing values into unused register bits has no effect. However, to ensure
software compatibility with future, feature-enhanced versions of the product,
unused register bits must be written with logic zero. Reading back unused
bits can produce either a logic one or a logic zero; hence, unused register bits
should be masked off by software when read.
2. Writeable test mode register bits are not initialized upon reset unless
otherwise noted.
11.1 Test Mode 0 Details
In test mode 0, the QDSX allows the logic levels on the digital device inputs to be
read through the microprocessor interface and allows the digital device outputs
to be forced to either logic level through the microprocessor interface. The IOTST
bit in the Master Test register must be set to logic one to access the device I/O.
To enable test mode 0, the IOTST bit in the Master Test register is set to logic
one, all normal mode registers should be set to their default state, and the
