Terminal Configuration and Functions

4.2

Signal Descriptions

The signal descriptions section shows pin information in module function order per package.

Section 4.2.1 and Section 4.2.2 identify 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/pulldown, whether the pin or ball can be configured as a

GIO, and a functional pin or ball description. The first signal name listed is the primary function for that

terminal (pin or ball). The signal name in Bold is the function being described. For information on how to

select between different multiplexed functions, see Section 4.3, Pin Multiplexing or see the I/O Multiplexing

and Control Module (IOMM) chapter of the RM44Lx 16/32-Bit RISC Flash Microcontroller Technical

Reference Manual (SPNU608).

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 high impedance 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 high

impedance.

In the Terminal Functions tables of Section 4.2.1 and Section 4.2.2, the RESET 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 terminal.
