This chapter describes the signals on each pin. When a lower case “n” is used at the beginning of the
signal name, it indicates that the signal is active low. For example, nRST indicates that the reset signal
is active low. The buffer type for each signal is indicated in the TYPE column, and a description of the
buffer types is provided in
Note 3.1
Note: The digital signals are not 5V tolerant.They are variable voltage from +1.6V to +3.6V, as shown

Unless otherwise noted in the pin description, internal pull-up and pull-down resistors are
always enabled. The internal pull-up and pull-down resistors prevent unconnected inputs
from floating, and must not be relied upon to drive signals external to
When connected to a load that must be pulled high or low, an external resistor must be
added.
