4.16 Test Automation Interface

The LaunchPad supports a 40-pin test automation header (687140183622 from Wurth) that allows an external
controller to manipulate some basic operations like power down, power on reset (POR), warm reset, boot mode
control and other functions.

Figure 4-28. Test Automation Header

Table 4-15. Test Automation Signal Description

Signal

Signal Type

Function

POWER_DOWN

GPIO

Instructs the LaunchPad to power down all
circuits

PORZn

GPIO

Creates a PORz into the AM243x

WARM_RESETn

GPIO

Creates a RESETz into the AM243x

GPIO3

GPIO

Disables the boot mode buffer

GPIO4

GPIO

Resets the bootmode IO expander

Bootmode_I2C

I2C

communicates with bootmode I2C buffer

I2C1

I2C

For internal testing

The test automation circuit has voltage translation circuits so that the controller is isolated from the IO voltages
used by the AM243x. Boot mode for the AM243x can be controlled by either the DIP switch or the test
automation header through the I2C IO expander.
