Warm Reset
The AK4651 initiates warm reset process by receiving a single pulse on the SYNC. The AK4651 clears PR4 bit and PR5
bit in the Power-down Control Register. However, warm reset does not influence PR0-3, 6 and 7 bits in Power-down
Control Register.
Note 41. SYNC signal should synchronize with BITCLK after AK4651 starts to output BITCLK clock.
Note 42. If an external clock is used, external clocks should be supplied before issuing a sync pulse for warm reset. ADC
and DAC require 1028TS for the initialization.

Note 43. All AC-link signals are normally low through the trailing edge of RESETN. Bringing RESETN high for the
rising edge of SDATAOUT causes the AK4651 AC-link outputs to go high impedance which is suitable for ATE
in circuit testing. Note that the AK4651 enters in the ATE test mode regardless SYNC is high or low.
Note 44. Once test modes have been entered, the only way to return to the normal operating state is to issue “cold reset”
which issues RESETN with both SYNC and SDATAOUT “L”.
