TMS570LS3137-EP 337ZWT_automotive_ball_map.gif

NOTE:

Balls can have multiplexed functions. Only the default function is depicted in above diagram, except for the EMIF signals that are multiplexed with ETM signals.

4.1.1 Pin Attributes

Section 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.

nPORRST W7 Input Pull Down 100uA Power-on reset, cold reset
External power supply monitor circuitry must drive nPORRST low when any of the supplies to the microcontroller fall out of the specified range. This terminal has a glitch filter.
See Section 6.8.
nRST B17 I/O Pull Up 100uA System reset, warm reset, bidirectional.
The internal circuitry indicates any reset condition by driving nRST low.
The external circuitry can assert a system reset by driving nRST low. To ensure that an external reset is not arbitrarily generated, TI recommends that an external pull-up resistor is connected to this terminal.
This terminal has a glitch filter. See Section 6.8.
nERROR B14 I/O Pull Down 20uA ESM Error Signal
Indicates error of high severity. See Section 6.18.
