Preliminary data sheet
Usage of the idle/turn-around time (IDCY) is demonstrated In
are added between a read and a write cycle in the same external memory device.
Address pins on the device are shared with other functions. When connecting external
memories, check that the I/O pin is programmed for the correct function. Control of these
settings is handled by the SCU.
