NOTE :

1)AA = Address of address register CA = Address of command register LCD = Load Command

LMA = Address of memory to be loaded

BA = Address of BufferRAM to load the data SA = Address of status register

2)“In progress” and “complete” refer to status register

3)Status reads in this figure is asynchronous read, but status read in synchronous mode is also supported.
