47 / 78 page  34COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD S6A0073 47 13) Read Busy Flag & Address RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 0 1 BF AC6 AC5 AC4 AC3 AC2 AC1 AC0 This instruction shows whether S6A0073 is in internal operation or not. If the resultant BF is High, the internal operation is in progress and should wait until BF becomes "LOW", which by then the next instruction can be performed. In this instruction value of address counter can also be read. 14) Write data to RAM RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 0 D7 D6 D5 D4 D3 D2 D1 D0 Write binary 8-bit data to DDRAM/CGRAM/SEGRAM. The selection of RAM from DDRAM, CGRAM, or SEGRAM, is set by the previous address set instruction : DDRAM address set, CGRAM address set, SEGRAM address set. RAM set instruction can also determines the AC direction to RAM. After write operation, the address is automatically increased/decreased by 1, according to the entry mode. 15) Read data from RAM RS R/W DB7 DB6 DB5 DB4 DB3 DB2 DB1 DB0 1 1 D7 D6 D5 D4 D3 D2 D1 D0 Read binary 8-bit data from DDRAM/CGRAM/SEGRAM. The selection of RAM is set by the previous address set instruction. If address set instruction of RAM is not performed before this instruction, the data that read first is invalid, because the direction of AC is not determined. If the RAM data several is read times without RAM address set instruction before read operation, the correct RAM data from the second, but the first data would be incorrect, as there is no time margin to transfer RAM data. In case of DDRAM read operation, cursor shift instruction plays the same role as DDRAM address set instruction : it also transfer RAM data to output data register. After read operation address counter is automatically increased/decreased by 1 according to the entry mode. After CGRAM/SEGRAM read operation, display shift may not be executed correctly. * In case of RAM write operation, after this AC is increased/decreased by 1 as in read operation after this. In this time, AC indicates the next address position, but the previous data can only be read by read instruction. |
