Note 1: All pin names with an overbar (e.g.,
RST) are active low.
Note 2: All pins, except power and analog pins, are CMOS/TTL, unless otherwise specified in the pin description.
PIN TYPES
I = input pin
IDIFF = input pin that is LVDS/LVPECL differential signal compatible
IPD = input pin with internal 50k pulldown
IPU = input pin with internal 50k pullup
I/O = input/output pin
IOPD = input/output pin with internal 50k pulldown
IOPU = input/output pin with internal 50k pullup
O = output pin
O3 = output pin that can be placed in a high-impedance state
ODIFF = output pin that is LVDS/LVPECL differential signal compatible
P = power-supply pin
Note 3: All digital pins, except OCn, are I/O pins in JTAG mode. OCn pins do not have JTAG functionality.
