TEST PINS (CONTINUED)
EMU0
I/O/Z
Emulator 0 pin. When TRST is driven low, EMU0 must be high for activation of the OFF condition.
When TRST is driven high, EMU0 is used as an interrupt to or from the emulator system and is
defined as input/output by way of the IEEE standard 1149.1 scan system.
EMU1/OFF
I/O/Z
Emulator 1 pin/disable all outputs. When TRST is driven high, EMU1/OFF is used as an interrupt
to or from the emulator system and is defined as input/output by way of the IEEE standard 1149.1
scan system. When TRST is driven low, EMU1/OFF is configured as OFF. The EMU1/OFF signal,
when active low, puts all output drivers into the high-impedance state. Note that OFF is used
exclusively for testing and emulation purposes (not for multiprocessing applications). Therefore,
for the OFF feature, the following apply:
TRST = low
EMU0 = high
EMU1/OFF = low
I = Input, O = Output, Z = High-impedance, S = Supply
memory
The ’5409 device provides both on-chip ROM and RAM memories to aid in system performance and integration.
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 1.
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 CPU and Peripherals Reference Set, Volume 1(literature number
SPRU131). When the security options are enabled, JTAG emulation is inhibited or nonfunctional.
