+ // This register is a bit tricky, but it allows testing of both

+ // two variants: a) writing to address 0 will store output data
+ // data value in the test register, b) writing to any non-zero
+ // address will store _address_ of write transaction in the test
+ // register.
+ //
+ // To test data bus, write some different patterns to address 0,
+ // then readback from any address and compare.
+ //
+ // To test address bus, write anything to some different non-zero
+ // addresses, then readback from any address and compare returned
