Resets and Interrupts
Resets
A reset immediately stops the operation of the instruction being
executed, initializes certain control bits, and loads the program counter
with a user-defined reset vector address. The following sources can
generate resets:
Power-on reset (POR) circuit
RESET pin
COP watchdog
Power-On Reset
A positive transition on the V
DD pin generates a power-on reset.
NOTE:
The power-on reset is strictly for power-up conditions and cannot be
used to detect drops in power supply voltage.
A 4064 t
CYC (internal clock cycle) delay after the oscillator becomes
active allows the clock generator to stabilize. If the RESET pin is at logic
0 at the end of 4064 t
CYC, the MCU remains in the reset condition until
the signal on the RESET pin goes to logic 1.
