General-Purpose IO 1
GPIO1: This signal is configured to be a general-purpose IO pin, or an alarm output
signal for port 1. This pin is an input after reset and should have a pullup resistor on it
if not connected to a signal or programmed as an output.
General-Purpose IO 2
GPIO2: This signal is configured to be a general-purpose IO pin, or the 8KREFO
output signal, or an alarm output signal for port 1. This pin is an input after reset and
should have a pullup resistor on it if not connected to a signal or programmed as an
output.
General-Purpose IO 3
GPIO3: This signal is configured to be a general-purpose IO pin, or an alarm output
signal for port 2. This pin is an input after reset and should have a pullup resistor on it
if not connected to a signal or programmed as an output.
General-Purpose IO 4
GPIO4: This signal is configured to be a general-purpose IO pin, or the 8KREFI input
signal, or an alarm output signal for port 2. When configured for 8KREFI mode the
signal frequency should be 8,000 Hz +/- 500 ppm and about 50% duty cycle. This pin
is an input after reset and should have a pullup resistor on it if not connected to a
signal or programmed as an output.
General-Purpose IO 5
GPIO5: This signal is configured to be a general-purpose IO pin, or an alarm output
signal for port 3. This pin is an input after reset and should have a pullup resistor on it
if not connected to a signal or programmed as an output.
General-Purpose IO 6
GPIO6: This signal is configured to be a general-purpose IO pin, or the TMEI input
signal, or an alarm output signal for port 3. When configured for TMEI input, the signal
low time and high time must be greater than 500ns. This pin is an input after reset
and should have a pullup resistor on it if not connected to a signal or programmed as
an output.
General-Purpose IO 7
GPIO7: This signal is configured to be a general-purpose IO pin, or an alarm output
signal for port 4.
This pin is an input after reset and should have a pullup resistor on it if connected to a
signal or programmed as an output.
General-Purpose IO 8
GPIO8: This signal is configured to be a general-purpose IO pin, or the PMU input
signal, or an alarm output signal for port 4. When configured for PMU input, the signal
low time and high time must be greater than 500ns. This pin is an input after reset
and should have a pullup resistor on it if not connected to a signal or programmed as
an output.
Test Enable (active low)
TEST: This signal enables the internal scan test mode when low. For normal operation
tie high. This is an asynchronous input.
High-Impedance Test Enable (active low)
HIZ: This signal puts all digital output and bidirectional pins in the high-impedance
state when it low and JTRST is low. For normal operation tie high. This is an
asynchronous input.
Reset (active low)
RST: This signal resets all the internal processor registers and logic when low. Global
and port data path resets are enabled and port power-downs are enabled. This pin
should be low while power is applied and set high after the power is stable. This is an
asynchronous input.
