Wake by an enabled interrupt
CPU halted (except for the interrupt logic)
Power-down mode blocks the internal clock inputs at the
Power down mode blocks the internal clock inputs at the
boundary of the CPU, preventing most of the CPU’s logic from
switching. During PD1, EDMA transactions can proceed between
peripherals and internal memory.

PD1
Wake by an enabled or
non-enabled interrupt

PD2
Wake by a device reset
Output clock from PLL is halted, stopping the internal clock
structure from switching and resulting in the entire chip being
halted. All register and internal RAM contents are preserved. All
functional I/O “freeze” in the last state when the PLL clock is
turned off.
011100
PD3
Wake by a device reset
Input clock to the PLL stops generating clocks. All register and
internal RAM contents are preserved. All functional I/O “freeze” in
the last state when the PLL clock is turned off. Following reset, the
PLL needs time to re-lock, just as it does following power-up.
Wake-up from PD3 takes longer than wake-up from PD2 because
the PLL needs to be re-locked, just as it does following power-up.

All others
When entering PD2 and PD3, all functional I/O remains in the previous state. However, for peripherals which are asynchronous in nature or
peripherals with an external clock source, output signals may transition in response to stimulus on the inputs. Under these conditions,
peripherals will not operate according to specifications.

4.6.2
C64x Power-Down Mode with an Emulator
If user power-down modes are programmed, and an emulator is attached, the modes will be masked to allow
the emulator access to the system. This condition prevails until the emulator is reset or the cable is removed
from the header. If power measurements are to be performed when in a power-down mode, the emulator cable
should be removed.
When the DSP is in power-down mode PD2 or PD3, emulation logic will force any emulation execution
command (such as Step or Run) to spin in IDLE. For this reason, PC writes (such as loading code) will fail.
A DSP reset will be required to get the DSP out of PD2/PD3.

Power-Supply Sequencing
TI DSPs do not require specific power sequencing between the core supply and the I/O supply. However,
systems should be designed to ensure that neither supply is powered up for extended periods of time
(
>
1 second) if the other supply is below the proper operating voltage.
4.7.1
Power-Supply Design Considerations
A dual-power supply with simultaneous sequencing can be used to eliminate the delay between core and I/O
power up. A Schottky diode can also be used to tie the core rail to the I/O rail (see Figure 4
8).
