TEST FEATURES DESCRIPTION

The D3MX contains test features for both production testing and board testing.

Simultaneously asserting the CSB, RDB and WRB inputs 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 D3MX. Test mode registers (as opposed to normal mode registers) are

selected when TRS (A[8]) is high.

Test mode registers may also be used for board testing. When all of the

constituent Telecom System Blocks within the D3MX 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).
