expired. The PLL reset time is the amount of wait time needed when resetting the PLL (writing PLLRST =

1), in order for the PLL to properly reset, before bringing the PLL out of reset (writing PLLRST = 0). For

the PLL3 reset time value, see Table 7-44. The PLL lock time is the amount of time needed from when the

PLL is taken out of reset to when the output clock is ready for use. The PLL3 lock time is given in

Table 7-44.

C = CLKIN3 cycle time in ns. For example, when CLKIN3 frequency is 25 MHz, use C = 40 ns.

7.10.2 PLL3 Controller Peripheral Register Descriptions

The memory map of the PLL3 controller is shown in Table 7-45. Note that only registers documented here

are accessible on the C6472. Other addresses in the PLL3 controller memory map should not be

modified.

7.10.3 PLL3 Controller Registers

This section provides a description of the PLL3 controller registers. For details on the operation of the PLL

controller module, see the TMS320C6472/TMS320TCI648x DSP Software-Programmable Phase-Locked

Loop (PLL) Controller User's Guide (literature number SPRU806).

NOTE

The PLL3 controller registers can only be accessed using the CPU or the emulator. Not all of

the

registers

documented

the

TMS320C6472/TMS320TCI648x

DSP

Software-Programmable Phase-Locked Loop (PLL) Controller User's Guide (literature

number SPRU806) are supported on the C6472. Only those registers documented in this

section are supported. Furthermore, only the bits within the registers described here are

supported. You should not write to any reserved memory location or change the value of

reserved bits.
