Mode 7: In this mode, the CKIO pin is an input, an external clock is input to this pin, and executes
waveform shaping, and also frequency multiplication according to the setting, by PLL circuit 1
before being supplied to this LSI. As PLL circuit 1 compensates for fluctuations in the CKIO pin
load, this mode is suitable for connection of synchronous DRAM.
