FUNCTION DESCRIPTION
System Interface
This chip has both kinds of interface type with MPU: 4-bit bus and 8-bits bus. 4-bit bus and 8-bit bus are selected
by the DL bit in the instruction register.
During read or write operation, two 8-bit registers are used. One is the data register (DR), and the other is the
instruction register (IR).
The data register (DR) is used as a temporary data storage place for being written into or read from
DRAM/CGRAM . Target RAM is selected by RAM address setting instruction. Each internal operation, reading
from or writing into RAM, is done automatically. After MPU reads DR data, the data in the next DDRAM/CGRAM
address is transferred into DR automatically. Also, after MPU writes data to DR, the data in DR is transferred into
DDRAM/CGRAM automatically.
The instruction register (IR) is used only to store instruction codes transferred from MPU. MPU cannot use it to
read instruction data.
To select a register, use RS input pin in 4-bit/8-bit bus mode.

Operation
Instruction Write operation (MPU writes instruction code into IR)
Read Busy flag (DB7) and address counter (DB0 - DB7)
Data Write operation (MPU writes data into DR)
Data Read operation (MPU reads data into DR)
Busy Flag (BF)
When BF = 1, it indicates that the internal operation is being processed. So during this time the next instruction
cannot be accepted. BF can be read, when RS = 0, and R/W = 1. (Read Instruction Operation), through DB7
port. Before executing the next instruction, be sure that BF is not 1.
