Detecting when LPC2000 is in debug mode
2005-09-29 by davebryan1
Hi, Does anyone have any ideas how to detect when a LPC2000 device has been halted by a JTAG debugger ? I need a fast acting signal (within a few microseconds) which can disable some logic elsewhere on the board. With other MCUs I've connected a retriggerable oneshot to a free-running timer o/p & when the CPU is stopped the timer's timebase is halted & the oneshot fails to retrigger. However, it seems that PCLK keeps running on the LPC2000 when the CPU is halted. Thanks Dave
