Figure 24. Setting timing of IPGA and ALC1 bits
(1) Set the zero cross time out period of IPGA as 128/fs: ZTM1-0 bits = “00”. (Note)
(2) Set the IPGA value of ALC1 operation start by IPGA6-0 bits.
(3) The value of IPGA6-0 bits is reflected to actual gain at zero crossing or zero cross time out.
(4) Set the zero cross time out period of ALC1 operation by ZTM1-0 bits after the zero cross time out period set by (1).
(5) Set ALC1 bit to “1”.
(Note) If ZTM1-0 bits are set to the value except for “00”, ALC1 bit must be set to “1” after this zero cross time out
period.
