MSCM_OCMDRn field descriptions (continued)
Field Description
27–24
OCMSZ
OCMEM Size. This read-only field provides an encoded value of the on-chip memory size. The capacity of
the memory is expressed as Size [bytes] = 2
(9+SZ)
where SZ is non-zero; a SZ = 0 indicates the memory is
not present.
0000 no OCMEMn
0011 4KB OCMEMn
0100 8KB OCMEMn
0101 16KB OCMEMn
0110 32KB OCMEMn
0111 64KB OCMEMn
1000 128KB OCMEMn
1001 256KB OCMEMn
1010 512KB OCMEMn
1011 1024KB OCMEMn
1100 2048KB OCMEMn
1101 4096KB OCMEMn
1110 8192KB OCMEMn
1111 16384KB OCMEMn
23–20
Reserved
This field is reserved.
19–17
OCMW
OCMEM datapath Width. This read-only field defines the width of the on-chip memory:
000-001 Reserved
010 OCMEMn 32-bits wide
011 OCMEMn 64-bits wide
100 OCMEMn 128-bits wide
101 OCMEMn 256-bits wide
110-111 Reserved
16
RO
Read-Only. This register bit provides a mechanism to “lock” the configuration state defined by
OCMDRn[11:0]. Once asserted, attempted writes to the OCMDRn[11:0] register are ignored until the next
reset clears the flag.
0 writes to the OCMDRn[11:0] are allowed
1 writes to the OCMDRn[11:0] are ignored
15–13
OCMT
OCMEM Type. This field defines the type of the on-chip memory:
000 Reserved
001 Reserved
010 Reserved
011 OCMEMn is a ROM.
100 OCMEMn is a program flash.
101 OCMEMn is a data flash.
110 OCMEMn is an EEE.
111 Reserved
12
OCMPU
OCMEM Memory Protection Unit. This read-only field identifies a memory protected by a Memory
Protection Unit.
0 OCMEMn is not protected by an MPU.
1 OCMEMn is protected by an MPU.
