Note that the usual pull up resistors associated with devices on

a IIC bus is integrated in the SA2005P IC. The SA2005P’s CL

input is a weak driver and can be overdriven by any external

signal. Loading of this pin with external circuitry may influence

the SA2005P's ability to reload its registers from the EEPROM.
