LTM1-0: ALC1 limiter operation period at zero crossing disable (see Table 25)
The IPGA value is changed immediately. When the IPGA value is changed continuously, the change is done
by the period specified by the LTM1-0 bits. Default is “00” (0.5/fs).

ZTM1-0: Zero crossing timeout for the write operation by the
μ
P, ALC1 recovery, and zero crossing enable (ZELM
bit = “0”) of the ALC1 operation (see Table 27)
When the IPGA performs zero crossing or timeout, the IPGA value is changed by the
μ
P WRITE operation,
ALC1 recovery operation or ALC1 limiter operation (ZELM bit = “0”).
Default is “00” (128/fs).
