2-Wire I
The I
output and test mode enable.
The PI6C185-02B, a slave receiver device, cannot be read back.
Sub addressing is not supported. To change one of the control
bytes, all preceding bytes must be sent.
Every byte put on the SDATA line must be 8-bits long (MSB first),
followed by an acknowledge bit generated by the receiving
device.
During normal data transfers, SDATA changes only when SCLK is
LOW. Exceptions: A HIGH to LOW transition on SDATA while
SCLK is HIGH indicates a “start” condition; a LOW to HIGH
transition on SDATA while SCLK is HIGH is a “stop” condition
and indicates the end of a data transfer cycle.

Each data transfer is initiated with a start condition and ended with
a stop condition. The first byte after a start condition is always a
7-bit address byte followed by a read/write bit. (HIGH = read from
addressed device, LOW = write to addressed device). If the device’s
own address is detected, PI6C185-02B generates an acknowledge
by pulling SDATA line LOW during ninth clock pulse, then
accepts the following data bytes until another start or stop condition
is detected.
Following acknowledgement of the address byte (0D2H), two more
bytes must be sent:
Although the data bits on these two bytes are “don’t care,” they
must be sent and acknowledged.
Note:
Stresses greater than those listed under MAXIMUM RATINGS
may cause permanent damage to the device. This is a stress rating
only and functional operation of the device at these or any other
conditions above those indicated in the operational sections of
this specification is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect reliability.
