9. OPERATION OF DUAL FUCTION PINS
Pin13 is dual function pins and are used for selecting different functions in this device (see Pin
description). During power up, these pins are in input mode (see Figure 1), therefore, and are
considered input select pins. When V
DD
reaches 2.5V, the logic level that is present on these pins are
latched into their appropriate internal registers. Once the correct information are properly latched,
these pins will change into output pins and will be pulled low by default. At the end of the power up
timer (within 3 ms) outputs starts to toggle at the specified frequency.

Each of these pins are a large pull-up resistor ( 250 K
@3.3V ) inside. The default state will be logic
1, but the internal pull-up resistor may be too large when long traces or heavy load appear on these
dual function pins. Under these conditions, an external 10 K
resistor is recommended to be
connected to V
DD
if logic 1 is expected. The same 10 K
connection to ground if a logic 0 is desired.
The 10 K
resistor should be place before the serious terminating resistor. Note that these logic will
only be latched at initial power on.
If optional EMI reducing capacitor are needed, they should be placed as close to the series
terminating resistor as possible and after the series terminating resistor. These capacitor has typical
values ranging from 4.7 pF to 22 pF.
