PWM Fault0 and Reset pin selection
The eZ8 CPU fetches the Reset vector at Program Memory addresses
and loads that value into the Program Counter. Program execution begins at the Reset
vector address. Following Stop Mode Recovery, the STOP bit in the

actions.
If the WDT times out during STOP mode, the device undergoes a SMR sequence. In the
Reset Status and Control
configured to generate a System Exception upon timeout, the eZ8 CPU services the WDT
System Exception following the normal Stop Mode Recovery sequence.
Each of the GPIO port pins may be configured as a Stop Mode Recovery input source. On
any GPIO pin enabled as a Stop Mode Recovery source, a change in the input pin value
(from High to Low or from Low to High) initiates Stop Mode Recovery. The GPIO Stop
Mode Recovery signals are filtered to reject pulses less than 10 ns (typical) in duration. In
the
Short pulses on the Port pin can initiate Stop Mode Recovery without initiating an interrupt
(if enabled for that pin).
The RESET pin can be set to function as a PWM Fault input. When selected, the RESET
input function is disabled. The
