Texas Instruments MSPM0G350 Series User Manual

(3) The start-up time is measured from the time that VDD crosses VBOR0- (cold start-up) to the time that the first instruction of the user
program is executed.

(1) The SYSOSC frequency correction loop (FCL) enables high SYSOSC accuracy via an external reference resistor (R
OSC
) which must
be connected between the device ROSC pin and VSS when using the FCL. Accuracies are shown for a ±0.1% ±25ppm R
OSC
; relaxed
tolerance resistors may also be used (with reduced SYSOSC accuracy). See the SYSOSC section of the technical reference manual
for details on computing SYSOSC accuracy for various R
OSC
accuracies. R
OSC
does not need to be populated if the FCL is not
enabled.
(2) Represents the device accuracy only. The tolerance and temperature drift of the ROSC resistor used must be combined with this spec
to determine final accuracy. Performance for a ±0.1% ±25ppm R
OSC
is given as a reference point.
(3) When SYSOSC is waking up (for example, when exiting a low power mode) and FCL is enabled, the SYSOSC will initially undershoot
the target frequency f
SYSOSC
by an additional error of up to f
settle,SYSOSC
for the time t
settle,SYSOSC
, after which the target accuracy is
achieved.
