7.28 Emulation and debugging
The LPC2478 implements two AHB in order to allow the Ethernet block to operate without
interference caused by other system activity. The primary AHB, referred to as AHB1,
includes the Vectored Interrupt Controller, GPDMA controller, USB interface, and 16 kB
SRAM.
The second AHB, referred to as AHB2, includes only the Ethernet block and an
associated 16 kB SRAM. In addition, a bus bridge is provided that allows the secondary
AHB to be a bus master on AHB1, allowing expansion of Ethernet buffer space into
off-chip memory or unused space in memory residing on AHB1.
In summary, bus masters with access to AHB1 are the ARM7 itself, the USB block, the
GPDMA function, and the Ethernet block (via the bus bridge from AHB2). Bus masters
with access to AHB2 are the ARM7 and the Ethernet block.
The LPC2478 includes up to 68 edge sensitive interrupt inputs combined with up to four
level sensitive external interrupt inputs as selectable pin functions. The external interrupt
inputs can optionally be used to wake up the processor from Power-down mode.
The memory mapping control alters the mapping of the interrupt vectors that appear at the
beginning at address 0x0000 0000. Vectors may be mapped to the bottom of the Boot
ROM, the SRAM, or external memory. This allows code running in different memory
spaces to have control of the interrupts.
The LPC2478 support emulation and debugging via a JTAG serial port. A trace port allows
tracing program execution. Debugging and trace functions are multiplexed only with
GPIOs on P2[0] to P2[9]. This means that all communication, timer, and interface
peripherals residing on other pins are available during the development and debugging
phase as they are when the application is run in the embedded system itself.
The EmbeddedICE logic provides on-chip debug support. The debugging of the target
system requires a host computer running the debugger software and an EmbeddedICE
protocol convertor. The EmbeddedICE protocol convertor converts the Remote Debug
Protocol commands to the JTAG data needed to access the ARM7TDMI-S core present
on the target system.
The ARM core has a Debug Communication Channel (DCC) function built-in. The DCC
allows a program running on the target to communicate with the host debugger or another
separate host without stopping the program flow or even entering the debug state. The
If level three Code Read Protection (CRP3) is selected, no future factory testing can be
performed on the device.
