Microcomputer interface Write Request pin
Microcomputer interface chip selector input pin (Pulldown)
Also used for SO control in addition to chip selection.
When only one AK7714 is used and SO is not used, CS="L" may be used
unchanged. SO and RDY will be Hi-z when CS ="H".
External condition jump pin (Pulldown)
Microcomputer interface serial data input pin (Pulldown)
Microcomputer interface serial data clock input pin
Clock output control pin (Pulldown)
Use of CTRL0 and CTRL1 allows the CLKO output and LRCLK/BITCLK
outputs
in the master mode to be fixed to “L” or “H”. See Function Description.
Reset pin
Normally, DSP RESET and CODEC RESET are simultaneously controlled for
use.
Reset pin (for initialization)
Used to input “L” to initialize the AK7714 at power-on.
