There are the following five clock modes to interface with external devices (see Table 1 and Table 2.)
Mode
PLL Master Mode (Note 22)
PLL Slave Mode 1
(PLL Reference Clock: MCKI pin)
PLL Slave Mode 2
(PLL Reference Clock: EXLRCK or EXBCLK pin)
EXT Slave Mode
EXT Master Mode (Note 23)
Note 22. If M/S bit = “1”, PMPLL bit = “0” and MCKO bit = “1” during the setting of PLL Master Mode, the invalid
Note 23. In case of EXT Master Mode, the register should be set as Figure 45.

The M/S bit selects either master or slave mode. M/S bit = “1” selects master mode and “0” selects slave mode. When the
AK5700 is power-down mode (PDN pin = “L”) and exits reset state, the AK5700 is slave mode. After exiting reset state,
the AK5700 goes to master mode by changing M/S bit = “1”.
