9 / 157 page TMS570LS3137-EP www.ti.com SPNS230D – OCTOBER 2013 – REVISED FEBRUARY 2015 4.1.1 Pin Attributes 4.1.1.1 identifies the external signal names, the associated pin/ball numbers along with the mechanical package designator, the pin/ball type (Input, Output, IO, Power or Ground), whether the pin/ball has any internal pullup/pulldown, whether the pin/ball can be configured as a GPIO, and a functional pin/ball description. The first signal name listed is the primary function for that terminal. The signal name in Bold is the function being described. Refer to the TMS570LS31X/21X Technical Reference Manual (SPNU499) for information on how to select between different multiplexed functions. NOTE All I/O signals except nRST are configured as inputs while nPORRST is low and immediately after nPORRST goes High. All output-only signals are configured as inputs while nPORRST is low, and are configured as outputs immediately after nPORRST goes High. While nPORRST is low, the input buffers are disabled, and the output buffers are tri-stated. In the Pin Functions table below, the "Default Pull State" is the state of the pullup or pulldown while nPORRST is low and immediately after nPORRST goes High. The default pull direction may change when software configures the pin for an alternate function. The "Pull Type" is the type of pull asserted when the signal name in bold is enabled for the given pin.
