Figure 1 Index Instruction
Status Read
The status read instruction reads the internal status of the HD66750/1.
L6D0:
Indicate the driving raster-row position where the liquid crystal display is being driven.
C5D0:
Read the contrast setting values (CT5D0).

Figure 2 Status Read Instruction
Start Oscillation
The start oscillation instruction restarts the oscillator from the halt state in the standby mode. After issuing
this instruction, wait at least 10 ms for oscillation to stabilize before issuing the next instruction. (See the
Standby Mode section.)
If this register is read forcibly when R/W = 1, 0750H is read.
