I2c row / collumn dot matrix display controller PCF8578/9

I think that I have figured something out, but I dont know how to write / send it....

  Wire.write(0xcd);             // set_mode  -blank


Wire.write(0xE4);             // device select
Wire.write(0X8F);             // load X address
Wire.write(0X70);             // RAM access
Wire.write(0xc4);             // DATA

Set mode works, but I don`t know how to send all other bytes at once. I think that my problem is that Every Wire.write sends the slave address and WRITE bit... I need that only before "device select" after that I only need ACK bit between the bytes...
SLAVE ADDRESS > WRITE BIT> ACK BIT> device select> ACK BIT> load-x-address> ACK BIT> RAM access> ACK BIT>DATA>ACK BIT....

Also I hope that this is the way to do it (light up a pixel). I have subaddresses for both 8579s.
