[4] Example of ALC Operation
The following registers should not be changed during the ALC operation.
LTM1-0, LMTH, LMAT, WTM1-0, ZTM1-0, RATT, REF7-0, ZELMN bits
The IPGA value of Lch becomes the start value if the IPGA value is different with Lch and Rch when the ALC starts.
Writing to the area over 80H (Table 17) of IPGL/R registers (04H, 05H) is ignored during ALC operation.
After ALC is disabled, the IPGA changes to the last written data by zero-crossing or time-out. In case of writing to
the
DATT area (Table 11) of DATT registers (08H, 09H), the DATT changes even if ALC is enabled.
PDN = “L”
“H”

Note : After ALC operation is disabled, the IPGA changes to the last written data during or before ALC operation.
