This section provides a description of the PLL2 controller registers. For details on the operation of the PLL
controller module, see the TMS320C645x DSP Software-Programmable Phase-Locked Loop (PLL)
Controller User's Guide (literature number
SPRUE56 ).
NOTE: The PLL2 controller registers can only be accessed using the CPU or the emulator.
Not all of the registers documented in the TMS320C645x DSP Software-Programmable Phase-Locked
Loop (PLL) Controller User's Guide (literature number
SPRUE56 ) are supported on the TMS320C6454.
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.
