Single-chip 16-bit/32-bit microcontrollers

entering the debug state. The debug communication channel is accessed as a

co-processor 14 by the program running on the ARM7TDMI-S core. The debug

communication channel allows the JTAG port to be used for sending and receiving data

without affecting the normal program ﬂow. The debug communication channel data and

control registers are mapped in to addresses in the EmbeddedICE logic. The JTAG clock

(TCK) must be slower than 1

⁄

6 of the CPU clock (CCLK) for the JTAG interface to operate.

6.18.2 RealMonitor

RealMonitor is a conﬁgurable software module, developed by ARM Inc., which enables

real time debug. It is a lightweight debug monitor that runs in the background while users

debug their foreground application. It communicates with the host using the DCC, which is

present in the EmbeddedICE logic. The LPC2101/02/03 contain a speciﬁc conﬁguration of

RealMonitor software programmed into the on-chip boot ROM memory.
