(2) Power supply startup sequence
Turn on the power by setting to INIT RESET = "L",DSP RESET = "L" and CODEC RESET = "L".
Then the AK7714 is initialized by setting to INIT RESET = "H". Note 1)
Initialization by INIT RESET is sufficient if it is done only when the power is turned on.
Note1: Set to INIT RESET = "H" after setting the oscillation when a crystal oscillator is used.
This setting time may differ depending on the crystal oscillator and its external circuit.
2: Do not stop the system clock (slave mode: XTI, LRCLK, BITCLK, master mode: XTI) except when
INIT RESET = "L".
If these clock signals are not supplied, too much current will flow because the dynamic logic is used internally,
and an operation failure may result.

INIT RESET
CODEC RESET
DSP RESET
When a crystal oscillator is used,
ensure stable oscillation in this
period.

DSP RESET and CODEC RESET can be controlled
simultaneously during normal use.
