7.4.4 Local Reset
The local reset can be used to reset a particular CorePac without resetting any other chip components.
Local reset is initiated by the following (for more details see the Phase Locked Loop (PLL) for KeyStone Devices User
Guide in ‘‘Related Documentation from Texas Instruments’’ on page 73:
•
•
LRESET pin
Watchdog timer should cause one of the below based on the setting of the CORESEL[2:0] and RSTCFG
register in the PLL controller. See ‘‘Reset Configuration Register (RSTCFG)’’ on page 147 and ‘‘CIC Registers’’

Hard Reset by requesting reset via PLLCTL
•
LPSC MMRs (memory-mapped registers)
7.4.5 Reset Priority
If any of the above reset sources occur simultaneously, the PLLCTL processes only the highest priority reset request.
The reset request priorities are as follows (high to low):
•
•
Power-on reset
Hard/soft reset
7.4.6 Reset Controller Register
The reset controller register are part of the PLLCTL MMRs. All C6678 device-specific MMRs are covered in Section
