TEST FEATURES DESCRIPTION
Simultaneously asserting (low) the CSB, RDB and WRB inputs when the MBEB
input is negated (low), causes all output pins and the data bus to be held in a
high-impedance state. This test feature may be used for board testing.
Test mode registers are used to apply test vectors during production testing of
the TUPP . Test mode registers (as opposed to normal mode registers) are
selected when A[7] is high.
Test mode registers may also be used for board testing. When all of the tributary
payload processors within the TUPP are placed in test mode 0, device inputs
may be read and device outputs may be forced via the microprocessor interface
(refer to the section "Test Mode 0" for details).
