NOTES: 20. The TMS and TCK pullup resistors are implemented in all C-, P-, and E-versions. The pullup resistor on TDI is implemented in
C-versions only.
21. Once the JTAG fuse is blown, no further access to the MSP430 JTAG/test feature is possible. The JTAG block switches to by-pass
mode.
22. The voltage supply to blow the JTAG fuse is applied to TDI/VPP pin when fuse blowing is desired.
