Reads enough bytes from slave with address to fill buffer

I2C Events (contract)
Master: ST SAD+R        MAK    MAK ...    NMAK SP
Slave:           SAK B0     B1     ... BN


  • ST = start condition
  • SAD+R = slave address followed by bit 1 to indicate reading
  • SAK = slave acknowledge
  • Bi = ith byte of data
  • MAK = master acknowledge
  • NMAK = master no acknowledge
  • SP = stop condition
