34COM/60SEG DRIVER & CONTROLLER FOR DOT MATRIX LCD
S6A0073
FUNCTION DESCRIPTION
System Interface
This chip has all three kinds of interface type with MPU : serial, 4-bit bus and 8-bit bus. Serial and bus(4-bit/8-bit)
are selected by IM input, and 4-bit bus and 8-bit bus are selected by DL bit in the instruction register. During read
or write operation, two 8-bit registers are used. one is data register (DR), the other is instruction register(IR). The
data register(DR) is used as temporary data storage place for being written into or read from
DDRAM/CGRAM/SEGRAM, target RAM is selected by RAM address setting instruction. Each internal operation,
reading from or writing into RAM, is done automatically. Hence, after MPU reads DR data, the data in the next
DDRAM/CGRAM/SEGRAM address is transferred into DR automatically. Also after MPU writes data to DR, the
data in DR is transferred into DDRAM/CGRAM/SEGRAM automatically. The Instruction register(IR) is used only
to store instruction code transferred from MPU. MPU cannot use it to read instruction data. To select register, use
RS/CS input pin in 4-bit/8-bit bus mode(IM = "High") or RS bit in serial mode(IM = "Low").
Table 2. Various Kinds of Operations according to RS and R/W Bits
RS R/W
Operation
L L Instruction Write operation (MPU writes Instruction code into IR)
L H Read Busy flag(DB7) and address counter (DB0 – DB6)
H L Data Write operation (MPU writes data into DR)
H H Data Read operation (MPU reads data from DR)
Busy Flag (BF)
When BF = "High", 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 = Low and R/W = High (Read Instruction Operation),
through DB7. Before executing the next instruction, be sure that BF is not High.
Display Data RAM (DDRAM)
DDRAM stores display data of maximum 80 × 8 bits (80 characters). DDRAM address is set in the address
counter (AC) as a hexadecimal number. (refer to Figure 1.)
