TYPICAL CHARACTERISTICS
JTAG fuse check mode
MSP430 devices that have the fuse on the TDI/VPP terminal have a fuse check mode that tests the continuity
of the fuse the first time the JTAG port is accessed after a power-on reset (POR). When activated, a fuse check
current, ITF, of 1 mA at 3 V, 2.5 mA at 5 V can flow from the TDI/VPP pin to ground if the fuse is not burned.
Care must be taken to avoid accidentally activating the fuse check mode and increasing overall system power
consumption.
Activation of the fuze check mode occurs with the first negative edge on the TMS pin after power-up or if TMS
is being held low during power-up. The second positive edge on the TMS pin deactivates the fuse check mode.
After deactivation, the fuse check mode remains inactive until another POR occurs. After each POR the fuse
check mode has the potential to be activated.

Care must be taken to avoid accidentally activating the fuse check mode, including guarding against EMI/ESD
spikes that could cause signal edges on the TMS pin.
