Power down mode
Power down mode is implemented using MLAT, MCK, and MDAT. When the MLAT is low the MDAT is goes to low,
the CD-MP3 goes to "power down reset" mode. It means power ON state. When the MLAT is low and the MCK goes
to LOW, the CD-MP3 toggles the "power down mode". The default value of MLAT, MCK, and MDAT is HIGH. When
the system power becomes ON and the master reset comes, Micom should set the value of MLAT, MCK, and MDAT
to HIGH. And should reset the power down mode of CD-MP3 using MLAT and MDAT LOW. Finally should send the
S/W reset to CD-MP3 H_SOFT_RST (8'hE0) register.
Sleep mode
In sleep mode, the minimal power is supplied which is needed just for DRAM refresh, receiving host command, and
etc. There is a register H_SLEEP_CR to control Sleep mode. To enter sleep mode write "1xxxxxxx" into the
H_SLEEP_CR. To wake up from sleep mode write "0xxxxxxx" into the H_SLEEP_CR.

Power Save mode
In power save mode, hardware units in the S5L9276X can be dynamically enabled or disabled during it's operation to
reduce the power consumption. This feature is enabled by writing xxxxxxx1 to H_PSV_ENABLE and disabled by
writing xxxxxx0 to H_PSV_ENABLE.
Make sure that Power Save mode should be disabled for
registers.
