Preliminary
FUNCTIONAL DESCRIPTIONS
DATA TRANSMISSION
The interface between KB2514 and MCU follows the I
2
C protocol. After the starting pulse, the transmission takes
place in the following order: Slave address with R/W bit, 2-byte register address, 2-byte data, and stop condition.
an acknowledge signal is received for each byte, excluding only the start/stop condition. The 2-byte register
address is composed of an 8-bit row address, and an 8-bit column address. The order of transmission for a 2-byte
register address is 'Row address
→
Column address'. The 2 bytes of data is because KB2514 has a 16-bit base
register configuration. KB2514's slave address is BAh. It is BBh in read mode, and BAh in write mode.
Address Bit Pattern for Display Registers Data
(a) row address bit pattern
R3 - R0: Valid data for row address
(b) Column address bit pattern
C4 - C0: Valid data for column address
X:Don't care bit
