Section 10 On-Chip Oscillation Circuits
Mode 7: In this mode, the CKIO pin is an input, an external clock is input to this pin, and
undergoes waveform shaping, and also frequency multiplication according to the setting, by PLL
circuit 1 before being supplied to this LSI. In modes 0 to 2, the system clock is generated from the
output of this LSI’s CKIO pin. Consequently, if a large number of ICs are operating on the clock
cycle, the CKIO pin load will be large. This mode, however, assumes a comparatively large-scale
system. If a large number of ICs are operating on the clock cycle, a clock generator with a number
of low-skew clock outputs can be provided, so that the ICs can operate synchronously by
distributing the clocks to each one.
As PLL circuit 1 compensates for fluctuations in the CKIO pin load, this mode is suitable for
connection of synchronous DRAM.
