VDD2 power ON delay
RESB input time
CSB input time
If the contents of internal registers are the same as default, the related commands can be ignored.
If RESB is held high or unstable during power ON, a successful hardware reset by RSTB is required after VDDI and
VDDA are both stable (as illustrated in Case-2). Otherwise, correct functionality can NOT be guaranteed.

VDDI and VDDA can be applied in any order. IC will
NOT be damaged when one of VDD1 and VDD2 is ON
but another is OFF.
Power stable is defined as the time that the later power
(VDDI or VDDA) reaches 90% of its rated voltage.
Recommend Setting: -50ms
RESB=L can be input at any time after power is stable.
t
RESB has priority over CSB.
Recommend Setting: 0
CSB can be input at any time after power is stable.
