Clock input pin.
Connect a 22.5792MHz or 24.576MHz crystal resonator as shown in the
example below: [Notes 2, 3]
When a crystal resonator is not used, feed a clock of 22.5792MHz or
24.576MHz to XIN pin. (Change the input clock frequency only when IC_N is at
“L” level.)
Clock output pin
Connect the external circuit as shown in the example below. [Note 3]
When an external clock is directly fed to XIN pin without a crystal resonator,
leave this pin open.
Use this pin only for clock generation.
Interrupt request output pin to the host controller.
(Interrupt request generating from DSP block)
Test pin
Connect this pin to the GND.
Control interface power supply ranging from 3.0V to 3.6V.
Core power supply ranging from 1.65V to 1.95V.
