Notes: 1. TTL Interface; MA0–MA15, RA0–RA4, DISPTMG, CUDISP, DB0–DB7, MCLK
C-MOS Interface; LU0–LU3, LD0–LD3, CL1, CL2, M, FLM
2. Input/output current is excluded. When input is at the intermediate level with CMOS, excessive
current flows through the input circuit to power supply. Input level must be fixed at high or low to
avoid this condition.
3. If the capacitive loads of LU0–LU3 and LD0–LD3 exceed the rating, noise over 0.8 V may be
produced on CUDISP, DISPTMG, MCLK, FLM and M. In case the loads of LU0–LU3 and LD0–
LD3 are larger than the ratings, supply signals to the LCD module through buffers.
