Peripheral Frame 1, Peripheral Frame 2, and Peripheral Frame 3 are grouped together to enable these blocks to be write/read peripheral block protected. The protected mode makes sure that all accesses to these blocks happen as written. Because of the pipeline, a write immediately followed by a read to different memory locations will appear in reverse order on the memory bus of the CPU. This action can cause problems in certain peripheral applications where the user expected the write to occur first (as written). The CPU supports a block protection mode where a region of memory can be protected so that operations occur as written (the penalty is extra cycles are added to align the operations). This mode is programmable, and by default, it protects the selected zones.
The wait-states for the various spaces in the memory map area are listed in Table 8-8.
AREA | WAIT-STATES (CPU) | COMMENTS |
---|---|---|
M0 and M1 SARAMs | 0-wait | Fixed |
Peripheral Frame 0 | 0-wait | |
Peripheral Frame 1 | 0-wait (writes) | Cycles can be extended by peripheral generated ready. |
2-wait (reads) | Back-to-back write operations to Peripheral Frame 1 registers will incur a 1-cycle stall (1-cycle delay). | |
Peripheral Frame 2 | 0-wait (writes) | Fixed. Cycles cannot be extended by the peripheral. |
2-wait (reads) | ||
Peripheral Frame 3 | 0-wait (writes) | Assumes no conflict between CPU and CLA. |
2-wait (reads) | Cycles can be extended by peripheral-generated ready. | |
L0 SARAM | 0-wait data and program | Assumes no CPU conflicts |
L1 SARAM | 0-wait data and program | Assumes no CPU conflicts |
