3.2.2 On-Chip ROM With Bootloader
A bootloader is available in the standard 5409 on-chip ROM. This bootloader can be used to automatically
transfer user code from an external source to anywhere in the program memory at power up. If the MP/MC
pin is sampled low during a hardware reset, execution begins at location FF80h of the on-chip ROM. This
location contains a branch instruction to the start of the bootloader program. The standard 5409 bootloader
provides different ways to download the code to accommodate various system requirements:
Parallel from 8-bit or 16-bit-wide EPROM
Parallel from I/O space 8-bit or 16-bit mode
Serial boot from serial ports 8-bit or 16-bit mode
Host-port interface boot
SPI serial EEPROM 8-bit boot mode
The standard on-chip ROM layout is shown in Table 35.

Interrupt vector table
In the VC5409 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.
3.2.3 On-Chip RAM
The 5409 device contains 32K
× 16-bit of on-chip dual-access RAM (DARAM). The DARAM is composed of
four 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. The DARAM is located in the address range 0080h7FFFh in data space, and can be
mapped into program/data space by setting the OVLY bit to one.
3.2.4 On-Chip Memory Security
The 5409 features a 16K-word
× 16-bit on-chip maskable ROM.
Customers can arrange to have the ROM of the 5409 programmed with contents unique to any particular
application. A security option is available to protect a custom ROM. The ROM and ROM/RAM security options
are available on the 5409. These security options are described in the TMS320C54x DSP Reference Set,
Volume 1: CPU and Peripherals (literature number SPRU131). When the security options are enabled, JTAG
emulation is inhibited or nonfunctional.
