■ Thermal Shutdown Function

When PMVCM bit is “1” and the internal device temperature rises up irregularly (E.g. Output pins of speaker amplifier

are shortened.), all amplifier blocks are automatically powered-down (PMLO, PMRO, PMRCV, PMHPL, PMHPR and

PMSPK bits = “0”) and then THDET bit becomes “1”. The other control registers are not initialized. When the internal

device temperature falls down, THDET bit becomes “0”, but the amplifier blocks do not return to normal operation unless

the amplifier blocks are powered-up (PMLO, PMRO, PMRCV, PMHPL, PMHPR or PMSPK bits = “1”). The device

status can be monitored by THDET bit.
