7.5.2 PLL Controller Memory Map
The memory map of the PLL Controller is shown in Table 7-14. TMS320C6678-specific PLL Controller register
definitions can be found in the sections following Table 7-14. For other registers in the table, see the Phase Locked
Loop (PLL) for KeyStone Devices User Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73.
CAUTION—Note that only registers documented here are accessible on the TMS320C6678. Other addresses
in the PLL Controller memory map including the reserved registers should not be modified. Furthermore,
only the bits within the registers described here are supported. Avoid writing to any reserved memory
location or changing the value of reserved bits. It is recommended to use read-modify-write sequence to
make any changes to the valid bits in the register.
