DB7-DB0
Quasi-Bidirectional I/O Data Bus.
Three state I/O common terminal.
DB0 (LSB) ... DB7 (MSB)
24
/RD(E)
When connected to an 8080 MPU, it is active LOW. This pad is
connected to the RD signal of the 8080MPU, and the NT7532 data bus
is in an output status when this signal is "L" When connected to a 6800
Series MPU, this is active HIGH. This is used as an enable clock input
of the 6800 series MPU
When connected to an 8080 MPU, this is active LOW. This terminal
connects to the 8080 MPU WR signal. The signals on the data bus are
latched at the rising edge of the WR signal. When connected to a 6800
Series MPU, this is the read/write control signal input terminal.
When W R/ = "H": Read
When W R/ = "L": Write
26
A0
Data or Instruction.
A0 = H
DB<0:7>: Display RAM data
A0 = L
DB<0:7>: Instruction data
27
/RES
14 16 RES I When RES is set to "L", the settings are initialized. The
reset operation is performed by the RES signal level
28
/CS1
This is the chip select signal. When CS1="L", then the chip select
becomes active, and data/command I/O is enabled.
