EXTCLK
Input
External clock
Input
When using external clock, used as clock
input pin. When using internal oscillator,
connect to VDD or VSS.
External clock
EXT_INT
Input
External/internal
oscillator clock
select
When EXT_INT = "High", external clock is
used. When "Low", internal oscillator is used.
VDD/VSS
RS
Input
Register select
Used as register selection input.
When RS = "High", Data register is selected.
When RS = "Low", Instruction register is
selected.
MPU
R/W
Input
Read/write
Used as read/write selection input.
When R/W = "High", read operation.
When R/W = "Low", write operation.
E
Input
Read/write
enable
Used as read/write enable signal.
DB0-DB3 Input/Output Data bus 0 - 7
When 8-bit bus mode, used as low order
bi-directional data bus.
During 4-bit bus mode open these pins.
DB4-DB7
When 8-bit bus mode, used as high order bi-
directional data bus. In case of 4-bit bus
mode, used as both high and low order.
DB7 is used for busy flag output during read
instruction operation.
RESETB
Input
Reset
If it is necessary to initialize the system by
hardware, force "Low", level signal to this
terminal about 1.2ms.
