Read (3) : 50h

The Read (3) mode has identical timing to that of Read (1) and (2) . However, while Read (1) and (2) are used

to access the array, Read (3) is used to access the 16 byte spare area. When the 50h command is executed,

the pointer will be set to an address space between columns 512 and 527. The values of Y will complete the

address decoding. During this operation, only address bits A3 to A0 are used to determine the starting column

address; A7 to A4 are ignored. A23 to A9 are used to determine the starting row address.

Figure 3 Read Mode (3) Operation

Sequential Read

Each RE pulse used to output data from the data register will cause the column address pointer to increment

by one. When the final column has been reached, the next page will be automatically loaded into the data register.

The R/B signal may be used to monitor the completion of the data transfer.
