Oscillator Delay: The total delay for the clock to be ready for various clock source selections are given in
Section 8.0 “Oscillator Configuration”
When the oscillator clock is ready, the processor begins execution from location 0x000000. The user application programs a GOTO
instruction at the Reset address, which redirects program execution to the appropriate start-up routine.
The Fail-Safe Clock Monitor (FSCM), if enabled, begins to monitor the system clock when the system clock is ready and the delay

When the device exits the Reset condi-
tion (begins normal operation), the
device operating parameters (voltage,
frequency, temperature, etc.) must be
within their operating ranges, otherwise
the device may not function correctly. The
user application must ensure that the
delay between the time power is first
applied, and the time SYSRST becomes
inactive, is long enough to get all
