NOTES:

1. TMS, TDI, and TCK pull-up resistors are implemented in all F versions.

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

3. The supply voltage to blow the fuse is applied to the TDI pin.

4. f(TCK) may be restricted to meet the timing requirements of the module selected. 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) = 33 x 1/f(FTG)

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

t(segment write end sequence) =5 x 1/f(FTG)

t(mass erase) = 5296 x 1/f(FTG)

t(segment erase) = 4817 x 1/f(FTG)
