TEST FEATURES DESCRIPTION
The TECT3 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 TECT3. Test mode registers (as opposed to normal mode registers) are
selected when TRS (A[13]) is high.
Notes on Register Bits:
1)
2)
Writing values into unused register bits has no effect. Reading back
unused bits can produce either a logic one or a logic zero; hence unused
bits should be masked off by software when read.
Writeable register bits are not initialized upon reset unless otherwise
noted.
