Notes:
1. A wide range of operating voltages is guaranteed, except in case of abrupt voltage fluctuations
during MPU access.
2. A0, D0~D7, E, R/W pins
3. CL, FR, M/S and RES pins
4. D0~D7
5. FR
6. A0, E (or RD), R/W (or WR), M/S and RES.
7. When D0 to D7 and FR are high impedance.
8. During continual writer access at a frequency of tcyc. Current consumption during access is
effectively proportional to the access frequency.
9. For a voltage differential of 0.1V between input (V1, …, V4) and output (COM, SEG) pins. All
voltages within specified operating voltage range.
10. PT6520 only. Does not include transient currents due to stray and panel capacitances.
