Figure 8.1. Jumper setting for Deep Sleep Current Testing
• Given an RCM programmed with NodeTest, execute the "shutdown" command:
> shutdown
Will wake from GPIO activity on the following port pins:
Port B, pin 6.
Port C, pin 6.
Entering SLEEPMODE_POWERDOWN via halSleep...
• Once the node is asleep, disconnect the Packet Trace Port cable, the DEI cable, the RS-232 cable, and remove all four UART jump-
ers (J22, J24, J25, and J26) from the Breakout Board between the USB and RS-232 connectors to obtain the lowest current set-
tings. All other jumpers may remain installed.
• Waking up is accomplished via either activity on the SerialWire debugger or pressing BUTTON0 or BUTTON1.
To measure deep sleep while the Packet Trace Port cable is still attached, issue the "swjdisable 1" command in NodeTest to disable
the SerialWire/JTAG port, and place the SWJ pins in a low current state. While the SWJ is disabled, the Packet Trace Port/debugger
will not be functional until either the command "swjdisable 0" is issued or the chip resets.
