4. Control Data Timing in Parallel Mode
Handling Pins for the Unused Mode when the CPU Interface is Specified
1. When Serial Mode is Specified
2. When Parallel Mode is Specified
Note:
**
1. The data values shown above are for the state immediately following a reset operation.
2. The INT-R pin (pin 35) signal is always output regardless of the mode.
3. Since the S/P pin (pin 42) has a built-in pull-up resistor, serial mode will be selected if it is left open.
