General purpose clock output. Divided system clock.
Operation mode. Mode = 0, Stand-alone mode; Mode =
1, Host-controlled mode.
Supply voltage.
Speaker output (+).
Reset. Active low input; resets the device when driven
low. May be used as a start input when device is used in
stand-alone mode.
Host interface status: asserted by KX1400 when
command execution is complete. Also used as MISO in
SPI pass-thru mode.
Host interface data request: asserted by KX1400 when
ready to receive next command/data from host.
