WTM1-0: ALC Recovery waiting time (see Table 14)
ZTM1-0: Zero crossing timeout (see Table 15)
LTM1-0: ALC Limiter period (see Table 16)

When the IPGA of each L/R channels perform zero crossing or timeout independently, the IPGA value is changed
by the P WRITE operation, ALC recovery operation or ALC limiter operation (ZELMN bit = “0”).
When ZELMN bit = “1”, the IPGA value is changed immediately. When the IPGA value is changed continuously,
the change is done by the period set by the LTM1-0 bits.
Register Name
Timer Select
A period of recovery operation when any limiter operation does not occur during the ALC operation.
