System Reset
Bringing the PDN pin = “L” sets the AK4126 power-down mode and initializes the digital filter. The AK4126 should be
reset once by bringing PDN pin = “L” upon power-up. When PDN pin = “L”, the SDTO output is “L”. The SDTO valid
time is 100ms. Until then, the SDTO outputs “L”. (SDTO shows SDTO1, SDTO2 and SDTO3. SDTI shows SDTI1,
SDTI2 and SDTI3.)
