MSP JTAG Device for MSP430 Microcontroller
used for programming / configuration of TI
MSP430 microcontroller
MSP-JTAG has an 3.0 Volt regulated output (VCCtool) supplied from
parallel port (LPT), which can be used to power target device (15mA). This is sufficient because MSP430 microcontroller only require 3-5mA.
If target device has it own supply, connect this supply to VCCsense.
Then output voltages of JTAG lines follow target device voltage.
