NOTES: 18. The TMS and TCK pullup resistors are implemented in all ROM(C), OTP(P) and EPROM(E) versions. The pullup resistor on TDI
is implemented in C versions only.
19. Once the fuse is blown no further access to the MSP430 JTAG/test feature is possible.
20. The voltage supply to blow the fuse is applied to TDI/VPP pin during the fuse blowing procedure.
