The data must not be written under 80H.
Writing to the area over 7FH (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.
