DMM WRITEREADBACKOFF command
Syntax
DMM WRITEREADBACKOFF
Purpose
DMM HCS12MERHANDLINGON command
Syntax
DMM HCS12MERHANDLINGON
Purpose
Not relevant for HCS08 and ColdFire cores. Enables the handling of Memory
Expansion Registers for HCS12 devices, i.e. INITRM, INITRG and INITEE. The
DMM remaps automatically memory range module addresses according to the real
value of these registers when halting.
NOTE The debugger does not poll the MER registers while running. Also the
remapping is performed only on factory defined memory range modules, not
user defined memory range modules.
DMM HCS12MERHANDLINGOFF command
Syntax
DMM HCS12MERHANDLINGOFF
Purpose
Not relevant for HCS08 and ColdFire cores. Disables completely the feature
here above.
