Description
Hold HIGH during normal operation. Connects to serial PROM
data in for RAM initialization. Connect to VCC if unused
Hold LOW during normal operation. Connects to serial PROM
reset for RAM initialization. Connect to GND if unused
Hold HIGH during normal operation. Connect to VCC if not used for
JTAG
Hold HIGH or LOW during normal operation. Connect to VCC or
ground if not used for JTAG
Connect to serial PROM clock for RAM initialization. Must be left
unconnected if not used for JTAG or RAM initialization
NOTE: All JTAG inputs are clamped to the VCC rail, not the VCCIO. Therefore, these pins can only be driven
up to VCC + 0.3 V. These input pins are LVCMOS2 compliant only (2.5 V). All JTAG outputs are driven by the
VCC rail, not VCCIO. Therefore, these output pins can only drive up to VCC + 0.3 V. These output pins are
LVCMOS2 compliant only (2.5 V).
