Introduction
External Expansion Interface (EEI) for connecting additional external
memory and peripherals.
Two serial port interfaces for exible peripheral congurations.
Codec Daughterboard(s) that supports up to eight channels of
real-time analog audio I/O.
Host Processor Interface (HPI) for connecting the EB402 to a host
microprocessor.
1.2 Operating Modes
The EB402 has three operating modes:
JTAG-Based Emulation
RS-232-Based Emulation
Stand-Alone Mode
The development and debug capabilities of JTAG- and RS-232-based
emulators are similar. Both modes provide access to all on-chip
resources. The device emulation unit (DEU) works in conjunction with
code residing in the boot ROM to provide full-speed in-circuit emulation,
and to allow full visibility and control of the device’s memory and registers.
The major differences between JTAG- and RS-232-based emulation are
communication speed, RS-232 stack requirements, and hardware debug
capabilities. JTAG-based emulation offers access to hardware debug
capabilities that are not available with RS-232-based emulation. Refer to
the ZSP SDK Software Development Kit User’s Guide for more
information about hardware debug capabilities.
1.2.1 JTAG Mode
The EB402 supports JTAG controllers from these manufacturers:
Corelis JTAG Controller
Macraigor Raven Controller
Check the ZSP web site (http://www.zsp.com) for the latest information
about compatible JTAG controllers and software.
