7.1.1 Reset Pin Description (RESB)
Hold the RESB at low for at least 80µs, after which the EM65101 accepts this reset
command.
7.1.2 Selection of Interface Type
(D15-D0), or serial data input (SDA, SCL). You can use the P/S pin to select the
parallel or serial interface. When the serial interface is selected, you are allowed to
write only as data reading is prohibited.
The EM65570 transfers data through the 8-bit parallel I/O (D7-D0), 16-bit parallel I/O

Display timing clock source select input pin.
CKS = “H”: Use external clock from the CK pin
CKS = “L”: Use the internal oscillated clock
The external clock input pin for display timing (CKS=1) or the internal clock output
pin for display timing (CKS=0).
When using the internal oscillator clock, CK must be floating (CKS=0)
