ACKS: Master Clock Frequency Auto Setting Mode Enable
0: Disable, Manual Setting Mode
1: Enable, Auto Setting Mode
Master clock frequency is detected automatically at ACKS bit “1”. In this case, the setting of DFS are
ignored. When this bit is “0”, DFS sets the sampling speed mode.
DFS: Sampling speed mode (see table 1.)
0: Normal speed
1: Double speed
Register bit of DFS is ORed with DFS pin if P/S = “L”.
The setting of DFS is ignored at ACKS bit “1”.
SDOS: SDTO source select
0: ADC
1: DAUX
Register bit of SDOS is ORed with SDOS pin if P/S = “L”.
SDOS should be set to “0” at TDM bit “1”.
LOOP1-0: Loopback mode enable
00: Normal (No loop back)
01: LIN LOUT1, LOUT2, LOUT3, LOUT4
RIN ROUT1, ROUT2, ROUT3, ROUT4
The digital ADC output (DAUX input if SDOS = “1”) is connected to the digital DAC input. In this
mode, the input DAC data to SDTI1-3 is ignored. The audio format of SDTO at loopback mode
becomes mode 2 at mode 0, and mode 3 at mode 1, respectively.
10: SDTI1(L) SDTI2(L), SDTI3(L), SDTI4(L)
SDTI1(R) SDTI2(R), SDTI3(R), SDTI4(R)
In this mode the input DAC data to SDTI2-4 is ignored.
11: N/A
LOOP1-0 should be set to “00” at TDM bit “1”.
