Description
2-Wire I2C Control
The I
2
C interface permits individual enable/disable of each clock
output and test mode enable.
The PI6C182B is a slave receiver device. It can not be read back.
Sub addressing is not supported. All preceding bytes must be sent
in order to change one of the control bytes.
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 SCLOCK
is LOW. Exceptions: A HIGH to LOW transition on SDATA while
SCLOCK is HIGH indicates a “start” condition. A LOW to HIGH
transition on SDATA while SCLOCK 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, PI6C182B 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 (D2), two more
bytes must be sent:
1. “Command Code” byte
2. “Byte Count” byte.
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 RAT-
INGS 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 ex-
tended periods may affect reliability.
