4 Terminal Configuration and Functions

4.1 PGE QFP Package Pinout (144-Pin)

Note: Pins can have multiplexed functions. Only the default function is depicted in above diagram.

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

RM46L852 337ZWT_non_automotive_ball_map.gifFigure 4-2 ZWT Package Pinout. Top View

Note: Balls can have multiplexed functions. Only the default function is depicted in above diagram.

4.3 Terminal Functions

Section 4.3.1 and Section 4.3.2 identify 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 I/O Multiplexing Module (IOMM) chapter of the RM46x Technical Reference Manual (SPNU514).

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.
