PRELIMINARY ( VER.2.1 )
FUNCTIONAL DESCRIPTIONS
SERIAL DATA INPUT AND TIMING
CK (Pin6), DATA (Pin7), EN (Pin8) terminals in S1T8825 are used for MCU serial data interface (MSB: 1st input
data; LSB: Last input data). Serial data controls the programmable reference divider, programmable divider (CH1),
programmable divider (CH2), and control latch separately by means of group code. Binary serial data is entered via
the DATA pin.
One bit of data is shifted into the internal shift register on the rising edge of the clock. When EN pin is high, stored
data is latched. The three terminals, CK, DATA, and EN, contain Schmitt trigger circuits to keep the data from
errors caused by noise, etc.
< Notice >
1. When power supply of S1T8825 is disconnected, CLK, DATA, EN port from MCU should be pulled low.
2. When power goes up first, R counter data should be entered earlier than N1 and N2 counter data.
3. When power goes up first, control data should be entered earlier than N1 and N2 counter data.

NOTE
: Start data input with MSB first
SERIAL DATA GROUP AND GROUP CODE
The S1T8825 can be controlled through 4 kinds of group selection. Each group is identified by selective a 2-bit
group code given below.
