Serial Data Input/Output (SDA) Input/Output pin for the 2-wire serial interface used for data transfer
Serial Clock Input (SCL) Input pin for the 2-wire serial interface used to synchronize data movement
on the serial interface.
REGISTER FUNCTIONS
The USER-PROGRAMMABLE REGISTERS can be programmed by the user to determine the mode
of operation(MUX) , operating frequency (DIV) and bus settings (BUS) . Details of how these registers
are programmed can be found in a later section; in this section the function of the registers are described.
The register setting are non-volatile, the values being stored automatically or as required in EEPROM
when the registers are programmed via the SDA and SCL pins.

DIV1 (bit)
This bit allows the output of the Prescaler P1 to be routed directly to the OUT1 pin (DIV1=1). The N
divider is
bypassed so the programmed value of
N is ignored. If DIV1=0 (default) the N divider
functions normally.
0M1, 0M0, 1M1, 1M0 (bits)
These bits set the prescalers P0 and P1 , to divide by 1, 2, 4, or 8. (Refer to Table 4)
