Select from the list of peripherals to freeze or unfreeze on program halt. The available peripherals are device dependent.
PIC12/16/18 MCU Devices
To freeze/unfreeze all device peripherals on halt, check/uncheck the “Freeze on Halt” checkbox. If this does not halt your desired peripheral, be aware that some peripherals have 'no freeze on halt' capability and cannot be controlled by the debugger.
dsPIC®, PIC24 and PIC32 Devices
Select the peripheral’s checkbox in the 'Peripherals to Freeze on Halt' list, to freeze it on a halt. Uncheck the peripheral to let it run while the program is halted. If you do not see a peripheral on the list, check 'All Other Peripherals'. If this does not halt your desired peripheral, be aware that some peripherals have no freeze on halt capability and cannot be controlled by the debugger.
To select all peripherals, including 'All Other Peripherals', click Check All. To deselect all peripherals, including 'All Other Peripherals', click Uncheck All.
