• Manufacturer: Sanyo Semiconductor Corporation

1) In modes (3), (4), and (5), the clock supplied from the XIN pin is used as the source.
2) Mode (3) applies to the state where an external clock other than CKOUT is supplied to XIN. If XIN pin and CKOUT
3) Mode (6) applies when the PLL circuit is locked.
4) In mode (7), the states immediatly before the setup is retained.
The table below summaries the low-power modes.
The table below lists the output pin states in the above modes.
pin are connected, no clock signals are output in this mode.
When the PLL circuit is unlocked, all circuits are stopped since no clock signal is supplied from XIN pin.
