ADSP-SC58x SMPU Interrupts
The SMPU has one interrupt with the SEC ID = 242. See the
rupt Controller (GIC) chapter for complete information on interrupt generation and use.
Memory Writes
A write transaction to address n is prevented when the following is true.
Address n is in memory region m and memory region m is write-protected (SMPU_RCTL[n].WPROTEN =1) and
ID is not a match. (See
tection and the ID comparison does not result in a match. If an ID comparison results in a match, the write transac-
tion is allowed through.
Memory Reads
A read transaction from address n is prevented when the following is true:
• Address n is in memory region and memory region m is read-protected (SMPU_RCTL[n].RPROTEN =1)
and
• ID is not a match
The block occurs because the memory region is configured for read-protection and the ID comparison does not
result in a match. If the ID comparison results in a match, the read transaction is permitted. (See
13–4
ID Comparison). The block occurs because the memory region is configured for write-pro-
