External Discharge mode

When the External Discharge arrangement is used, a logic-level (DIS) pin is connected to an external resistor (Rdis) that can be used to control the discharge of the Capacitors.  A typical value for Rdis is 100 kΩ.  This value of Rdis will give a discharge current of approximately 1.1V/(100 kΩ) = 11 μA.  The case C shows this arrangement.  The Resistive drive option on the X and Yk lines can be optionally enabled or disabled with this arrangement.  When the Resistive drive is option is not enabled, it is recommended to use 1 kΩ resistors on X and Yk Lines external to the UC3L device.
