Description
Reset Input
Holding this pin high for 64 oscillator periods while the oscillator is
running resets the device. The Port pins are driven to their reset
conditions when a voltage lower than V
oscillator is running.
This pin has an internal pull-down resistor which allows the device to be
reset by connecting a capacitor between this pin and V
Asserting RST when the chip is in Idle mode or Power-Down mode
returns the chip to normal operation.
Test Input
Test mode entry signal. This pin must be set to V
