7 Mask-Programmable Options
The DSP1629 contains a ROM that is mask-programmable. The selection of several programmable features is
made when a custom ROM is encoded. These features select the input clock options, the instruction/coefficient
memory map option, and the hardware emulation or ROM security option, as summarized in Table 59.
7.1 Input Clock Options
For all input options, the input clock CKI can run at some fraction of the internal clock frequency by setting the PLL
multiplication factors appropriately (see Section 4.12, Clock Synthesis). When the PLL is bypassed, the input clock
CKI frequency is the internal clock frequency.
7.2 Memory Map Options
The DSP1629 offers a DSP1629x16 or a DSP1629x10 where the difference is in the memory maps. The
DSP1629x16 contains 16 Kwords of internal RAM (DPRAM). The DSP1629x10 supports the use of only 10 Kwords
of DPRAM. See Section 4.4 Memory Maps and Wait-States for further description.
7.3 ROM Security Options
The DSP1600 hardware development system (HDS) provides on-chip in-circuit emulation and requires that the re-
locatable HDS code be linked to the application code. This code's object file is called 1629hds.v#, where # is a
unique version identifier. Refer to the DSP1629-ST software tools release for more specific information. If on-chip
in-circuit emulation is desired, a nonsecure ROM must be chosen. If ROM security is desired with the DSP1629, the
HDS cannot be used. To provide testing of the internal ROM contents on a secure ROM device, a cyclic redundancy
check (CRC) program is called by and linked with the user's source code. The CRC code resides in the first
4 Kwords of ROM.
See the DSP1600 Support Tools Manualfor more detailed information.

(# indicates the current version number) is the relocatable HDS object code. It uses approximately 140 words
and must reside in the first 4 Kwords of ROM.
crc16.v#is the cyclic redundancy check object code. It uses approximately 75 words and must reside in the first 4 Kwords
of ROM. See the DSP1600 Support Tools Manual or detailed information.
