Terminal Functions

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 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 TMS570LS31x/21x 16/32-Bit RISC Flash Microcontroller

Technical Reference Manual (SPNU499) .

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.
