EM65565A
The Reset Circuit
When the /RST input falls to “L”, these LSI reenter their default state. The default settings
are shown below:
1. Display OFF
2. Normal display
3. ADC select: normal (ADC command D0 = 0)
4. Power control resister: (D2, D1, D0) = (0,0,0)
5. Serial interface internal register data clear
6. LCD power supply bias ratio: 1/9 bias
7. Read-modify-write OFF
8. Static indicator OFF: Static indicator register: (D1, D2) = (0,0)
9. Display start line set to first line
10. Column address set to address 0
11. Page address set to page 0
12. Common output status normal
13. V0 voltage regulator internal power supply ratio set mode clear
V0 voltage regulator internal resistor ratio register: (D2, D1, D0) = (1,0,0)
14. Electronic volume register set mode clear
Electronic volume register: (D5, D4, D3, D2, D1, D0) = (1,0,0,0,0,0)
15. Test mode clear
On the other hand, when the reset command is used only default settings 7 to 15 above
are put into effect. The /RST terminal is connected to the MPU reset terminal, making the chip
reinitialize simultaneously with the MPU. At the time of power up, it is necessary to reinitialize
using the /RST terminal.
In the EM65565A, if the internal liquid crystal power supply circuit is not used, then it is
necessary to apply an “L” signal to the /RST terminal when the external liquid crystal power
supply is applied.
Even though the oscillator circuit operates while the /RST terminal is “L” the display
timing generator circuit is stopped, and the DCLK, FR, FRS, and /BCT terminals are fixed to
“H”. There is no influence on the D0 to D7 terminals.
