9.2.3.8 Reset Status (RESET_STAT) Register
The Reset Status Register (RESET_STAT) captures the status of local reset (LRx) for each of the cores
and also the global device reset (GR). Software can use this information to take different device
initialization steps.
• In case of local reset: The LRx bits are written as 1 and the GR bit is written as 0 only when the C66x
CorePac receives a local reset without receiving a global reset.
• In case of global reset: The LRx bits are written as 0 and the GR bit is written as 1 only when a
global reset is asserted.
The Reset Status Register is shown in the figure and table below.
