Figure 2–8 illustrates one example procedure for a complete power down of the TLC320AD90C. From
normal operation, sequential writes to the General Purpose register are performed to power down the
TLC320AD90C one section at a time. After all of the other sections have been shut down, a final write (of
PR4) can be executed to shut down the TLC320AD90C digital interface (AC-Link). The device remains in
sleep mode with all registers holding their static values. To wake up the TLC320AD90C, the digital controller
sends a pulse on SYNC which issues a warm reset. This operation restarts the TLC320AD90C digital
interface (resets PR4 to zero). The TLC320AD90C can also be awakened with a cold reset. A cold reset
causes a loss of the register values since a cold reset sets the registers back to their default states. When
a section is powered back on, the Power Down register (index 26h) should be read to verify that the section
is ready (i.e., stable) before any operation that requires the section is attempted.

Figure 2–9 illustrates an example procedure where all of the mixers are operational with the static volume
settings contained in their associated registers. This procedure is used when a CD is played (or external
LINE_IN source) through the TLC320AD90C to the speakers but most of the system is in low-power mode.
This procedure follows the previous procedure except that the analog mixer is never shut down.
