2.5.4 Automation and Control Connector [J50_CP]

The EVM supports an interface to allow for automated control of the system, including functions like on/off, reset, and boot mode settings.

Table 2-16 Test Automation Interface Pin Definition [J50]
Pin # Pin Name Description Dir
1 Power Power, 3.3 V Output
2 Power Power, 3.3 V Output
3 Power Power, 3.3 V Output
4-6 <open>
7 GND Ground
8-15 <open>
16 GND Ground
17-24 <open>
25 GND Ground
26 POWERDOWNz EVM Power Down Input
27 PORz EVM Power-On/Cold Reset (MCU_PORz) Input
28 RESETz EVM Warm Reset (RESETz) Input
29 <open>
30 INT1z EXTINT / GPIO0_0 Input
31 INT2z WKUP_GPIO0_7 Bi-Dir
32 <open>
33 BOOTMODE_RSTz Bootmode Buffer Reset Input
34 GND Ground
35 <open>
Note: In the DIR, column, output is to the test automation controller, input is from the automation controller. Bi-Dir signals can be configured as either input or output.
Note: The Signal polarity is defined with a trailing 'z' in the Pin Name, which indicates the signal is active LOW. For example, POWERDOWNz is an active low signal, meaning '0' = EVM is Powered Down, '1' = EVM is NOT Powered Down.
