PCM I/F Master Mode/Slave Mode
The PLLBT2 bit selects either master or slave mode (
Table 80
). When either PCM I/F A or PCM I/F B is set in slave
mode, the other is set in master mode. (For example, when PCM I/F B is set in slave mode, PCM I/F A is set in master
mode.) When the AK4671 is power-down mode (PDN pin = “L”) or PMPCM bit = “0”, each clock pins (SYNCA,
BICKA, SYNCB, BICKB) of PCM I/F become a Hi-Z (
Table 81
).
PLLBT3-0 bits should be set when PMPCM bit = “0” to avoid shorting out of the slave mode clock pins and master mode
clock output.
After setting the PDN pin = “H”, the PCM I/F clock pins are the Hi-Z state until PMPCM bit becomes “1”. The PCM I/F
clock pins of master mode should be pulled-down or pulled-up by the resistor (about 100k
Ω
) externally to avoid the
floating state.
