(the document you are reading at the moment) is CPU specific, while all other parts of the online help are generic for all CPUs supported by Lauterbach. So if there are questions related to the CPU, the Processor Architecture Manual should be your first choice.
There is no restriction in the number of software breakpoints. On-chip Breakpoints The resources for the on-chip breakpoints are provided by the CPU. The following list gives an overview of the on-chip breakpoints for the XC800: • On-chip breakpoints: Total amount of available on-chip breakpoints.
Extended Operation (EO) register before executing the next GO command. • The XC800 extends the 8051 instruction set with the special command MOVC @(DPTR++),A to write data (e.g. from a I2C LPC memory IC) into program RAM. As the 8051 instruction set is only 8 bit wide, and there were no unused opcodes available, the TRAP opcode 0A5h is re-used for this instruction.
