8.3.3 Serial data transfer
Serial data can be inputted when the Strobe goes to “0”.
Serial data consists of 2 bytes. The first byte (Start Byte) consists of a total of 8 bits: the
Synchronous bits (bit1-bit5), R/W (bit6), RS (bit7) and bit8. The register is selected (Instruction
Register or Data Register) by the RS (bit7). RS is “0” in Instruction Register, and it is “1” in
Data Register. The data write or read is selected by R/W (bit6). R/W is “0” when the data is
written, and it is “1” when the data is read.
In “Data Write”, the second byte (8-bit Instruction / Data Byte) is written after the Start Byte.
On the other hand, the second byte is the read data in “Data Read”, such as the Busy Flag +
Address Counter or the data written in the DD RAM or CG RAM. The read data is outputted at
the falling edge of the shift clock.
