principle characteristics of the DCO

DIndividual devices have a minimum and maximum operation frequency. The specified parameters for fDCOx0 to fDCOx7 are valid for all devices.

DThe DCO control bits DCO0, DCO1 and DCO2 have a step size as defined in parameter SDCO.

DThe modulation control bits MOD0 to MOD4 select how often fDCO+1 is used within the period of 32 DCOCLK cycles. fDCO is used for the remaining cycles. The frequency is an average = fDCO ⋅ (2MOD/32).

DThe ranges selected by RSel4 to RSel5, RSel5 to RSel6, and RSel6 to RSel7 are overlapping.

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)
