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(8+SZ) where SZ is non-zero; a SZ = 0 indicates the memory
is not present.
0000 no OCMEMn
0100 4KB OCMEMn
0101 8KB OCMEMn
0110 16KB OCMEMn
0111 32KB OCMEMn

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
100-111 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 OCMEMn is a system RAM.
001 OCMEMn is a graphics RAM.
010 Reserved
011 OCMEMn is a ROM.
