NOTES: 23. The power source to blow the fuse is applied to TDI pin.

24. Once the JTAG fuse is blown, no further access to the MSP430 JTAG/test feature is possible. The JTAG block is switched to bypass

mode.

25. f(TCK) may be restricted to meet the timing requirements of the module selected.
26. Duration of the program/erase cycle is determined by f(FTG) applied to the flash timing controller. It can be calculated as follows:

t(word write) = 35 x 1/f(FTG)
t(segment write, byte 0) = 30

×

1/f(FTG)

t(segment write, byte 1 – 63) = 20

×

1/f(FTG)

t(mass erase) = 5297 x 1/f(FTG)
t(page erase) = 4819 x 1/f(FTG)
