PINS AND USAGE TAB
Display how the MCLR pin will be used, either as master clear or
an input port pin.
Connect/disconnect the resistor on the MPLAB ICE 4000 header
used to pull up the MCLR pin.
Warning: Disconnecting may lock up the emulator hardware.
Display a Warning message if MCLR voltage level is low. This
would indicate a problem, as the pull-up should be keeping the
level high.
The purpose of this check box is to keep the emulator from
changing external bus access methods during the “halted” state of
the emulator when using Extended Microcontroller mode.
Generally, the emulator would change external bus access
methods to the most efficient method for the emulator during Halt.
However, this process tri-states the external bus, causing the bus
and control lines to float. This may cause problems for the target
system.
By selecting “Preserve user's external bus access method when
halted”, the bus stays active during “halted” states. This may cause
the emulator's response to be slightly slower and there will be bus
activity generated by the emulator system.
Connect/disconnect the resistor on the MPLAB ICE 4000 header
used to pull up the MCLR pin.
Warning: Disconnecting may lock up the emulator hardware.
This feature not yet implemented.
For target dsPIC device in proper mode, emulate using target
device.
