11.1 I/O Test Mode
PMCTST:
In I/O test mode, the TUPP allows the logic levels on the device inputs to be read
through the microprocessor interface, and allows the device outputs to be forced
to either logic level through the microprocessor interface.
To enable I/O test mode, the IOTST bit in the Master Test register is set to
logic 1.
Reading the following address locations returns the values for the indicated
inputs :

Writing the following address locations forces the outputs to the value in the
corresponding bit position:

PROPRIETARY AND CONFIDENTIAL TO PMC-SIERRA, INC., AND FOR ITS CUSTOMERS’ INTERNAL USE
The PMCTST bit is used to configure the TUPP for PMC's manufacturing
tests. When PMCTST is set to logic 1, the TUPP microprocessor port
becomes the test access port used to run the PMC "canned" manufacturing
test vectors. The PMCTST bit is logically "ORed" with the IOTST bit, and can
only be cleared by setting CSB to logic 1.
