IDPDRn—I/O Data Path Diagnostic Registers
Address
BB + 2A80, 2180, 2280, 2380
Access
R/W
The IDPDRn registers can be programmed by diagnostics to force
errors on the TLSB and Turbo Vortex buses for the I/O port to de-
tect. System bus errors are transmitted on the TLSB and are de-
tected by the I/O port when the signals are received back. These
registers can also be used to force errors to be generated across
the Down Turbo Vortex buses.
These registers are physically located in the four IDR data path
gate arrays IDR0–3, respectively, of the I/O port.
