4 Terminal Configuration and Functions

4.1 PGE QFP Package Pinout (144-Pin)

RM48L952 PGE_144A_pns160.gif
A. Pins can have multiplexed functions. Only the default function is depicted in the figure.

4.2 ZWT BGA Package Ball-Map (337-Ball Grid Array)

RM48L952 337ZWT_non_automotive_ball_map.gif
A. Balls can have multiplexed functions. Only the default function, except for the EMIF signals that are multiplexed with ETM signals, is depicted in the figure.
Figure 4-2 ZWT Package Pinout. Top View(A)

Note: Balls can have multiplexed functions. Only the default function is depicted in Figure 4-2, except for the EMIF signals that are multiplexed with ETM signals.

4.3 Terminal Functions

Section 4.3.1 and Section 4.3.2identify the external signal names, the associated pin or ball numbers along with the mechanical package designator, the pin or ball type (Input, Output, I/O, Power, or Ground), whether the pin or ball has any internal pullup or pulldown, whether the pin or ball can be configured as a GPIO, and a functional pin or ball description. The first signal name listed is the primary function for that terminal. The signal name in bold is the function being described. For information on how to select between different multiplexed functions, see the RM48x 16/32-Bit RISC Flash Microcontroller Technical Reference Manual (SPNU503) .

NOTE

In the Terminal Functions table below, the "Reset Pull State" is the state of the pull applied to the terminal 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 terminal by the IOMM control registers.


All I/O signals except nRST are configured as inputs while nPORRST is low and immediately after nPORRST goes High. While nPORRST is low, the input buffers are disabled, and the output buffers are disabled with the default pulls enabled.


All output-only signals have the output buffer disabled and the default pull enabled while nPORRST is low, and are configured as outputs with the pulls disabled immediately after nPORRST goes High.

TERMINAL SIGNAL
TYPE		 RESET PULL
STATE		 PULL TYPE DESCRIPTION
SIGNAL NAME 337 ZWT
nPORRST W7 Input Pulldown Fixed 100-µA
Pulldown		 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 Pullup Fixed 100-µA
Pullup		 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 pullup resistor is connected to this terminal.
This terminal has a glitch filter. See Section 6.8.
nERROR B14 I/O Pulldown Fixed 20-µA
Pulldown		 ESM Error Signal
Indicates error of high severity. See Section 6.18.
