Dot Character VFD Controller/Driver IC
POWER ON RESET
When PT6314 is initialized, the internal status after power supply has been reset is as follows:
1. Display Clear: 20H (space code) fills the DDRAM
2. Address Counter is set to 00H
3. Address Counter is pointed to the DDRAM
4. Display ON/OFF: D=0, C=0, B=0 (Display OFF)
5. Entry Mode Set: I/D=1, S=0 (Increment, Cursor Shifts are enabled)
6. Function Set: DL=1, N=1 (8-Bit MCU Interface, 2-Line Display are enabled.)
7. Brightness Control: BR0=BR1=0 (Brightness = 100%)
For the MCU Interface and Duty Ratio Selection, please refer to the table below.
The above table shows the relationship between the status of PT6314 and the pin states during
RESET.
