Measurement Circuits

The following conditions apply to figure 1.

• Standby mode

• Port S input resistors enable

• I/O ports in output mode, all outputs HIGH

• INT open and internal input transistors enabled

• External pull-down resistor connected to RES.

• Current flow through components connected to LCD

ports is not included.

• fxtal = 32 to 65 kHz

• fcer = 200 kHz to 4 MHz

The flowing conditions apply to figures 2 and 3.

• fxtal = 32 kHz

• C1 = C2 = C3 = 0.1µF

• LCD ports are open.

• fcer = 200 kHz to 4 MHz
