\label{MEM_8h_a2}


Size in bytes of a register dump. 

This is the size of a CPU register dump. There are 32 32-bit GPRs, 32 64-bit FPRs and 68 32-bit SPRs. That adds up to 656 bytes (164 words). A little extra space is allocated here (768 bytes, 192 words) in case a register or two was missed and needs to be added later.

For Memory Dump commands, a snapshot of the processor register values are gathered and stored in the dump context at the time the dump is started. The register values are then retrieved from the context as the dump progresses.

Memory map selection. 

Enumerated types to select a memory map. This is derived from the memory dump and load telecommands and describes three types of memory accesses made by the LAT memory system:

MEMORY - regular byte-accessable RAM-like memories with no alignment requirements.

PCI\_\-CFG - PCI configuration space.

REGISTER - PPCI memory-mapped registers. Memory map may contains \char`\"{}holes\char`\"{}, so generic non-aligned bytes access not always allowed.
