Power and Sleep Controller (PSC) Module
The Power and Sleep Controller (PSC) controls DM6446 device power by turning off unused power
domains or gating off clocks to individual peripherals/modules. The PSC consists of a Global PSC (GPSC)
and a set of Local PSCs (LPSCs). The GPSC contains memory mapped registers, power domain control,
PSC interrupt control, and a state machine for each peripheral/module. An LPSC is associated with each
peripheral/module and provides clock and reset control. The GPSC controls all of DM6446’s LPSCs. The
ARM subsystem does not have an LPSC module. ARM sleep mode is accomplished through the wait for
interrupt instruction. The LPSCs for DM6446 are shown in Table 6-5. The PSC register memory map is
given in Table 6-6. For more details on the PSC, see the TMS320DM644x DMSoC ARM Subsystem
Reference Guide (literature number SPRUE14).
