In the 5410A ROM, 128 words are reserved for factory device-testing purposes. Application code to be implemented in on-chip ROM
must reserve these 128 words at addresses FF00h-FF7Fh in program space.
The 5410A device contains 64K-word
×
16-bit of on-chip dual-access RAM (DARAM).
The DARAM is composed of eight blocks of 8K words each. Each block in the DARAM can support two
reads in one cycle, or a read and a write in one cycle. Four blocks of DARAM are located in the address
range 0080h-7FFFh in data space, and can be mapped into program/data space by setting the OVLY bit
to one. The other four blocks of DARAM are located in the address range 18000h-1FFFFh in program
space. The DARAM located in the address range 18000h-1FFFFh in program space can be mapped into
data space by setting the DROM bit to one.
The TMS320VC5410A device has a maskable option to protect the contents of on-chip memories.
When the
RAM/ROM
security option is selected, the following restrictions apply:
Only the on-chip ROM-originating instructions can read the contents of the on-chip ROM. On-chip RAM
and external RAM-originating instructions cannot read data from ROM; instead, 0FFFFh is read. Code
can still branch to ROM from on-chip RAM or external program memory.
The contents of on-chip RAM can be read by all instructions, even by instructions fetched from external
memory. To protect the internal RAM, the user must never branch to external memory.
The security feature completely disables the scan-based emulation capability of the 54x to prevent the
use of a debugger utility. This only affects emulation and does not prevent the use of the JTAG
boundary scan test capability.
The device is internally forced into microcomputer mode at reset (MP/MC bit forced to zero),
preventing the ROM from being disabled by the external MP/MC pin. The status of the MP/MC bit in
the PMST register can be changed after reset by the user application.
HPI writes have no restriction, but HPI reads are restricted to the 4000h - 5FFFh address range.
