Microcomputer Interface
The microcomputer interface offers a choice of parallel or serial operation. The configuration is determined by the input
levels at the AD4 to AD6 pins (pins 49 to 51) at the rising edge of the RESET pin (pin 38) input.
Parallel interface setting conditions
[AD6, AD5, AD4] = [0, 1, 0]: Data read at rising edge of STB pin (pin 44) input.
[AD6, AD5, AD4] = [0, 1, 1]: Data read at falling edge of STB pin (pin 44) input.
[AD6, AD5, AD4] = [0, 0, 0]: Data read while STB pin (pin 44) input at high level.
Serial interface setting conditions
[AD6, AD5, AD4] = [1, *, *]
Notes: 1. Do not use any mode specifications other than the above.
2. A reset (RESET = low) configures the AD0 to AD7 pins (pins 45 to 52) for input.
3. The serial input mode fixes the AD2 to AD7 pins in input mode. Always treat them as input pins (by
connecting them to either ground or DV
DD
1). If the interface is used for serial operation, the AD6 pin may be
fixed at high level without any problems.
4. The RESET pin (pin 38) includes a built-in pul-up resistor. Do not apply a voltage higher than DV
DD
1.
