A stable oscillator can be constructed simply by connecting an AT-cut crystal and two capacitors to XG and XD, as shown in the figure below. If the oscillator frequency is increased, CD and CG should be decreased proportionally. Note that the circuit board lines to XG and XD must be as short as possible to prevent wiring capacitance from changing the oscillator frequency or increasing the power consumption. RA8835 XG XD CG CD CD=3 to 20 pF CG=2 to 18 pF Load impedance =700? (max) Figure 7-4: Crystal Oscillator 7-7 Status Flag The RA8835A series has a single bit status flag. D6: X line standby Figure 7-5: Status Flag The D6 status flag is HIGH for the TC/R-C/R cycles at the end of each line where the RA8835A series is not reading the display memory. The microprocessor may use this period to update display memory without affecting the display, however it is recommended that the display be turned off when refreshing the whole display.
