3.52inch e-Paper V1.1 User Manual 6-4-3 MCU Serial Interface (3-wire SPI) The 3-wire serial interface consists of serial clock SCLK, serial data SDIN and CSB. In 3-wire SPI mode, SCL acts as SCLK, SDA acts as SDIN. The operation is similar to 4-wire serial interface while D/C pin is not used. There are altogether 9 bits will be shifted into the shift register on every ninth clock in sequence: D/C bit, D7 to D0 bit. - Page 14 3.52inch e-Paper V1.1 User Manual Figure 6-4-4: Serial interface characteristics Vdd - VSS = 2.4V to 3.3V, TOPR = 25°C, CL=20pF Parameter Symbol Min.
