(m)Write Data to CG, DD or MK RAM

By the execution of this instruction, the binary 8-bit data (A7 to A0) are written into the DD RAM, and the binary 5-

bit data (A4 to A0) are written into the CG or MK RAM. The selection of RAM is determined by the previous in-

struction. After this instruction execution, the address increment (+1) or decrement(-1) is performed automatically

according to the entry mode set. And the display shift is also executed according to the previous entry mode set.

However, the data in MK RAM (1C)H and (1D)H are not displayed, bat the automatic address increment is per-

formed. And the display is not changed by the data written into MK RAM (1C)H and (1D)H

Read data key is a instruction for data reading out of keyscan. However, the bit 8 to 15 are input data. After this 8-

bit data were input, the operation change to output from input at the falling edge of 8th SCK clock.
