electrical characteristics over recommended ranges of supply voltage and operating free-air
temperature (unless otherwise noted) (continued)
principle characteristics of the DCO
Individual devices have a minimum and maximum operation frequency. The specified parameters for
f
DCOx0
to f
DCOx7
are valid for all devices.
The DCO control bits DCO0, DCO1 and DCO2 have a step size as defined in parameter S
DCO
.
The modulation control bits MOD0 to MOD4 select how often f
DCO+1
is used within the period of 32 DCOCLK
cycles. f
DCO
is used for the remaining cycles. The frequency is an average = f
DCO
× (2
MOD/32
).
The ranges selected by R
Sel4
to R
Sel5
, R
Sel5
to R
Sel6
, and R
Sel6
to R
Sel7
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

may be restricted to meet the timing requirements of the module selected.
26. Duration of the program/erase cycle is determined by f
