PAS6311LT Datasheet, PDF (11/18 Pages) Pixart Imaging Inc. – CMOS VGA DIGITAL IMAGE SESNSOR

PAS6311LT Specification
During read cycle, the master generates start condition and then place the 1^st byte data that are combined
slave address ( 7 bits ) with a read / write control bit to SDA line. After issue acknowledgment, 8 bits
DATA was also placed on SDA line by PAS6311LT. The 8 bits data was read from PAS6311LT internal
control register that address was assigned by previous write cycle. Follow the master acknowledgment,
the PAS6311LT place the next 8 bits data ( address is increment automatically ) on SDA line and then
transmit to master serially. The DATA and Am cycles is repeat until the last byte read. After last byte
read, Am is no longer generated by master but instead by keep SDA line high. The slave ( PAS6311LT )
must releases SDA line to master to generate STOP condition.
