1: When the CPU operating rate is 100% (no HALT state).

2: All SEGs: off waveform, No LCD panel load, 1/3 bias, 1/3 duty, Frame frequency: Approx. 64 Hz, Bias voltage multiplying clock:

1/128 LSCLK (256Hz)

3 : 32.768KHz crystal resonator DT-26 (Load capacitance 6pF) (made by KDS:DAISHINKU CORP.) is used (CGL=CDL=6pF)

4 : Significant bits of BLKCON0 to BLKCON4 registers are all “1” except DLCD bit on BLKCON4.

5 : Recommended operating temperature (Ta=-20 to 70°C, Ta=-40 to 85°C for P version)

6: LCD stop mode, 1/3 bias, Bias voltage multiplying clock: 1/128 LSCLK (256Hz)
