When the SMP Discharge mode arrangement is used, a logic-level (SMP) pin is connected to the capacitors through external high value resistors for the discharge of the capacitors. The case D 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 1kOhm resistors on X and Yk Lines external to the UC3L device.
