SYStem.Option.ICREAD Read from instruction cache
Default: OFF:
If enabled, Data.List window and Data.dump window for access class P: (program memory) display the
memory values from the instruction cache L2 cache if valid. If the data is not available in cache, the physical
memory will be displayed.
SYStem.Option.IMASKASM Disable interrupts while single stepping
Default: OFF.
If enabled, the interrupt mask bits of the CPU will be set during assembler single-step operations. The
interrupt routine is not executed during single-step operations. After single step the interrupt mask bits are
restored to the value before the step.
SYStem.Option.IMASKHLL Disable interrupts while HLL single stepping
Default: OFF. If enabled, the interrupt mask bits of the cpu will be set during HLL single-step operations. The
interrupt routine is not executed during single-step operations. After single step the interrupt mask bits are
restored to the value before the step.
Format: SYStem.Option.ICREAD [ON | OFF]
Format: SYStem.Option.IMASKASM [ON | OFF]
Format: SYStem.Option.IMASKHLL [ON | OFF]
NOTE: Do not enable this option for code that disables MSR_EE. The debugger will
disable MSR_EE while the CPU is running and restore it after the CPU stopped. If a
part of the application is executed that disables MSE_EE, the debugger cannot
detect this change and will restore MSE_EE.
