C Bus Address Setting Pin 1 (I2CSEL pin = “H”)
C Bus Data Clock Pin (I2CSEL pin = “H”)
C Bus Data Clock Pin (I2CSEL pin = “H”)
Connect to the C_N pin of the AK6514C (EEPROM).The output is Hi-Z when
EESEL pin= “L”.
Connect to the SO pin of the AK6514C (EEPROM).
Connect to DVSS or leave open when a EEPROM is not use.
Connect to the SCK pin of the AK6514C (EEPROM). The output is Hi-Z when
EESEL pin = “L”.
Connect to the SI pin of the AK6514C. The output is Hi-Z when EESEL pin=
“L”.
Connect to AVSS.
When initial reset state and Microcomputer interface are not in use, leave RQ_N
pin= “H”.
When RQ_N pin = “H”, SO pin= Hi-Z
When SI is not used, tie the SI pin = “L”.
When SCLK is not used, tie the SCLK pin = “H”.
Leave open. SDA goes “L”.
Leave open. Normally TESTO1 goes “L”.
