Description
VCC
-
POWER leads intended for external connection to a VCC board
plane.
GND
-
GROUND leads intended for external connection to a GND board
plane.
a. R indicates state during reset.
b. Can also be programmed as Byte Enable for both Read/Write in Rev B2.
2.1 Test Mode Pins
Several device pins are used during manufacturing test to put the V292PBC 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:
