Hold the RESB low for at least 10µs, then the EM65571 accepts this reset
command.
I/O (D15-D0) or serial data input (SDA, SCL). The parallel interface or serial
interface can be selected by the state of the P/S pin. When selecting serial
interface, data reading cannot be performed, only data writing can operate.
The EM65571 transfers data through an 8-bit parallel I/O (D7-D0), 16-bit parallel

Display timing clock source select input pin.
CKS = “H”: Use external clock from the CK pin.
CKS = “L”: Use internal oscillator clock.
In the case of TCP, draw it as a separate terminal.
External clock input pin for display timing (CKS=1).
When using internal oscillator clock, connect CK to VSS (CKS=0).
External power supply pin for EEPROM programming or erasing.
When using external power for EEPROM programming or erasing, the
power supply is 16V~18V.
