1. Parallel interface
The parallel interface uses the following two input pins and eight I/O pins.
AS/DS pin (pin 43: input): Address/data select input. low = address; high = data.
STB pin (pin 44: input): Strobe signal input for address input and data I/O.
AD0 pin (pin 45 : I/O): Address input and data I/O
AD1 pin (pin 46 : I/O): Address input and data I/O
AD2 pin (pin 47 : I/O): Address input and data I/O
AD3 pin (pin 48 : I/O): Address input and data I/O
AD4 pin (pin 49 : I/O): Address input and data I/O
AD5 pin (pin 50 : I/O): Address input and data I/O
AD6 pin (pin 51 : I/O): Address input and data I/O
AD7 pin (pin 52 : I/O): Address input and data I/O
Note: The address cannot be read.
1-1Address and data transfer procedures
The command address is assigned to the lowest seven bits of the address. The most significant bit (AD7) is used to
specify write or read. The address can only be written. It cannot be read.
Writing data
Drive the AS/DS pin (pin 43) at low level to specify address input.
Specify the address in the lowest seven bits. Set the top bit to 0.
Drive the STB pin (pin 44) at high level to cause the LSI to read the address.
The parallel interface mode can be configured to read input using a choice of three different timings.
— Data read at rising edge of STB pin input.
— Data read at falling edge of STB pin input.
— Data read while STB pin input at high level.
Drive the AS/DS pin (pin 43) at high level to specify data I/O.
Drive the STB pin (pin 44) at high level to cause the LSI to read the data.
