Peripherals
The ARM9 has access to all of the peripherals on the DM6467T device.
3.3.10 PLL Controller (PLLC)
The ARM Subsystem includes the PLL Controller. The PLL Controller contains a set of registers for
configuring DM6467T’s two internal PLLs (PLL1 and PLL2). The PLL Controller provides the following
configuration and control:

configuration and control:
•
PLL Bypass Mode
•
Set PLL multiplier parameters
•
Set PLL divider parameters
•
PLL power down
•
Oscillator power down
The PLLs are briefly described in this document in the Clocking section. For more detailed information on
the PLLs and PLL Controller register descriptions, see the TMS320DM646x DMSoC ARM Subsystem

3.3.11 Power and Sleep Controller (PSC)
The ARM Subsystem includes the Power and Sleep Controller (PSC). Through register settings
accessible by the ARM9, the PSC provides two levels of power savings: peripheral/module clock gating
and power domain shut-off. Brief details on the PSC are given in

3.3.12 ARM Interrupt Controller (AINTC)
The ARM Interrupt Controller (AINTC) accepts device interrupts and maps them to either the ARM’s IRQ
(interrupt request) or FIQ (fast interrupt request). The ARM Interrupt Controller is briefly described in this
document in the Interrupts section. For detailed information on the ARM Interrupt Controller, see the
TMS320DM646x DMSoC ARM Subsystem Reference Guide (literature number
