2.1 Test Mode Pins

Several device pins are used during manufacturing test to put the V350EPC device into various test

modes. These pins must be maintained at proper levels during reset to insure proper operation.

This is typically handled through pull-up or pull-down resistors (typically 1K to 10K) on the signal pins if

they are not guaranteed to be at the proper level during reset. Table 4 below shows the reset states for

test mode pins:
