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 : Use 32.768KHz Crystal Oscillator C-001R (Epson Toyocom) with capacitance C

GL/CDL＝0pF.

4 : Use 4.096MHz Crystal Oscillator CHC49SFWB (Kyocera).

5 : Significant bits of BLKCON0~BLKCON4 registers are all “1”.
