ISD51 In-System Debugger
Top 3 Articles
ISD51 (In-System Debugger) is a new debug monitor technology for 8051 user programs. ISD51 consists of a configurable debug module that you link to your user programs to provide support for program testing via the 8051 on-chip UART.
The software and hardware requirements of ISD51 are minimal. It can run from external or on-chip CODE space and requires no special hardware components like von Neumann-wired memory.
ISD51 works on both very small 8051 devices like the Philips LPC series and on complete systems that have access to the full CODE and XDATA address space.
ISD51 is available starting with C51 Version 6.23. It is available only in the PK51 Professional Developer's Kit.
Complete documentation for the ISD51 In-System Debugger is available on the Keil web site.
