2.11.10 Test Automation Header

The AM263Px Control Card supports a 40 pin test automation header that allows an external controller to manipulate basic operations such as power down, PORz, warm reset, and bootmode control.

The Test Automation Circuit is powered by a dedicated 3.3 V power supply (VSYS_TA_3V3) that is generated by a 5 V to 3.3 V buck regulator (TPS62177DQCR).

The AM263Px SoC I2C2 instance is connected to both the Test Automation Header and the bootmode IO expander (TCA6408ARGTR).

Table 3-23 details the Test Automation GPIO mapping:

Table 2-23 Test Automation Header GPIO Mapping
Signal Name Description Direction
TA_POWERDOWN when logic low, disables the 3.3 V buck regulator (TPS62913RPUR) that is used in the first stage of DC/DC conversion Output
TA_PORZn when logic low, connects the PORz signal to ground due to the PMOS V_GS being less than zero creating a power on reset to the MAIN domain Output
TA_RESETz when logic low, connects the WARMRESETn signal to ground due to the PMOS V_GS being less than zero creating a warm reset to the MAIN domain Output
TA_GPIO1 when logic low, connects the INTn signal to ground due to the PMOS V_GS being less than zero creating an interrupt to the SoC Output
TA_GPIO3 when logic low, disables the bootmode buffer output enable Output
TA_GPIO4 Reset signal for Bootmode IO Expander (TCA6408ARGTR) Output
