Byte1: SDRAM Active/Inactive Register
(1 = enable, 0 = disable)
Byte2: Optional Register for Possible Future
Requirements (1 = enable, 0 = disable)
2-Wire I2CControl
The I2C interface permits individual enable/disable of each clock
output and test mode enable.
The PI6C184 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 bite 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, PI6C184 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, and
2. “Byte Count” byte.
Although the data bits on these two bytes are “don’t care,” they
must be sent and acknowledged.
