Reset Input
The Port pins are driven to their reset conditions when a voltage lower
than V
This pin has an internal 10K pull-up resistor which allows the device to
be reset by connecting a capacitor between this pin and VSS.
Asserting RST when the chip is in Idle mode or Power-Down mode
returns the chip to normal operation.
The output is active for at least 12 oscillator periods when an internal
reset occurs.
