16.9.2 Blinking display (Alternately displaying A-pattern and B-pattern area data)
constant-period interrupt (INTRTC) timing of the real-time counter (RTC). Refer to CHAPTER 7 REAL-TIME COUNTER
about the setting of the RTC constant-period interrupt (INTRTC) timing.
(Example: Set 1 to bit 0 of 00H, and set 0 to bit 4 of F0400H for blinking display.) When not setting blinking display of the
LCD, set the same values. (Example: Set 1 to bit 2 of F0402H, and set 1 to bit 6 of F0402H for lighting display.)

Refer to 16.4 LCD Display Data Memory about the display area.
Next, the timing operation of display switching is shown.
When BLON = 1 has been set, A-pattern and B-pattern area data will be alternately displayed, according to the
For blinking display of the LCD, set inverted values to the B-pattern area bits corresponding to the A-pattern area bits.
