3.3.7 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, if desired.
•
In case of local reset:
The LRx bits are written as 1 and GR bit is written as 0 only when the CorePac receives
an local reset without receiving a global reset.
•
In case of global reset:
The LRx bits are written as 0 and GR bit is written as 1 only when a global reset is
asserted.
The Reset Status Register is shown in
3.3.8 Reset Status Clear (RESET_STAT_CLR) Register
The RESET_STAT bits can be cleared by writing 1 to the corresponding bit in the RESET_STAT_CLR register. The
Reset Status Clear Register is shown in
