DZFM3-0: Zero detect mode select (Table 16)
Initial: “1111”, disable
LOOP1-0: Loopback mode enable
00: Normal (No loop back)
01: LIN1 → LOUT1, LOUT2
RIN1 → ROUT1, ROUT2
LIN2 → LOUT3, LOUT4
RIN2 → ROUT3, ROUT4
LIN3 → LOUT5, LOUT6
RIN3 → ROUT5, ROUT6
The digital ADC output is connected to the digital DAC input. In this mode, the input DAC data to
SDTI1-6 are ignored. The audio format of SDTO at loopback mode becomes mode 3 at mode 0 or 1,
and mode 5 at mode 2, respectively.
10: SDTI1(L) → SDTI2(L), SDTI3(L), SDTI4(L), SDTI5(L), SDTI6(L)
SDTI1® → SDTI2®, SDTI3®, SDTI4®, SDTI5®, SDTI6®
In this mode, the input DAC data to SDTI2-6 are ignored.
11: Not Available
LOOP1-0 should be set to “00” at TDM mode.
