TITLE: Reset Application on EM55000 serial
REVISED DATE
: 1, August, 2001
REVISED VERSION
: 1.1
APPLY TO CHIPS
: All EM55200~EM55700
APPLY TO SOFTWARE : All
SEE ALSO:
1. EM55000 series chip has a internal reset circuit when external
Provided power (VDD) below its minimum value.
It also provide a pin RESET to do reset from external circuit.
This pin has an internal pull-low resistor. If external apply
voltage above 1/2 VDD on RESET pin, it enable reset function.
When chip is in reset condition, its I/O pins become Hi-z state.
2. Normal The Reset pin is no-use with open this pin, For internal
reset.
3. A typical reset circuit is shown as below.
4. A typical external reset circuit with push button
is shown as below.
