FUNCT ION DES CRIPT ION
BUS INTERFACE
Data are transmitted to and from the microprocessor to the PT2258 via the SDA and SCL. The SDA
and SCL make up the BUS Interface. It should be noted that the pull-up resistors must be connected to
the positive supply voltage.
DATA VALIDITY
A data on the SDA Line is considered valid and stable only when the SCL Signal is in HIGH State. The
HIGH and LOW States of the SDA Line can only change when the SCL signal is LOW. Please refer to
the figure below.

START AND STOP CONDITIONS
A Start Condition is activated when
1. the SCL is set to HIGH and
2. SDA shifts from HIGH to LOW State.
The Stop Condition is activated when
1. SCL is set to HIGH and
2. SDA shifts from LOW to HIGH State.
Please refer to the timing diagram below.

BYTE FORMAT
Every byte transmitted to the SDA Line consists of 8 bits. Each byte must be followed by an
Acknowledge Bit. The MSB is transmitted first.
