RSVD
Description
Reserved (Read Only).
Data Memory Subsystem Stall Address Calculation Unit (Read Only). DM wants no
more requests from AC.
Floating Point Stall (Read Only). FP is stalling the pipeline.
Floating Point Error (Read Only). FP is reporting an error.
Floating Point Busy (Read Only). FP is reporting that it is not idle.
Instruction Pipeline Busy (Read Only). IP is reporting that it is not idle.
Data Memory Subsystem Busy (Read Only). DM is reporting that it is not idle.
Instruction Fetch Busy (Ready Only). IF is reporting that it is not idle.
Data Memory Subsystem Execution Delay (Read Only). Pipeline is waiting for DM to
provide instruction data.
Instruction Queue Empty (Read Only). Instruction Queue is empty.
Wait for Floating Point Interrupt (Read Only). Processor is waiting for an external
maskable interrupt due to a FP error (CR0 NE bit is set, See Table 5-10 "CR0 Bit
Descriptions" on page 96). (Default = 0)
Flushing (Read Only). Processor is flushing the pipeline while waiting for DM to empty.
Halted (Read Only). Processor is halted. (Default = 0)
Suspended (Read Only). Processor is suspended. (Default = 0)
Non-Maskable Interrupt Active. Processor is in a NMI handler. (Default = 0)
Debug Management Mode. Processor is in debug management mode. (Default = 0)
System Management Mode. Processor is in system management mode. (Default = 0)
