Timing Characteristics
7.9.1
Startup, Reset, and Wake-up Timing
The startup, reset, and wake-up timings are calculated using the following formula:
Where
and
are found in Table 7-44.
is the delay relative to RCSYS,
is the period of the CPU clock. If another clock source than RCSYS is selected as CPU
clock the startup time of the oscillator,
, must be added to the wake-up time in the
stop, deepstop, and static sleep modes. Please refer to the source for the CPU clock in the
”Oscillator Characteristics” on page 56 for more details about oscillator startup times.
