10.2.3 Program

Table 10-4. Program Option Category
Erase All Before Program	Enabling this option will cause the entire device to be erased prior to programming the data from MPLAB X IDE. Any memory areas designated to be preserved will be read before the device is erased and reprogrammed on the device when the device is programmed. Unless programming new or already erased devices, it is important to have this box checked. If not checked, the device is not erased and program code will be merged with the code already in the device.
Programming mode entry	This option designates the method the debugger will use to put the target device in programming mode. For the low-voltage method, V_PP will not exceed the V_DD supply voltage. Instead a test pattern will be used on V_PP. For the high-voltage method, a voltage in excess of 9 volts will be placed on V_PP. Note: High voltage programming requires V_DD above 2.8V. Select low voltage programming if your target voltage is below 2.8V. High voltage program mode entry - 2.8 to 5.0V. Low voltage program mode entry only - 1.2 to 5.0V.
LED Brightness Setting	Select the level of brightness from 1 (darkest) to 10 (brightest).
PGC Configuration	This option determines the type of resistance that will be applied to the PGC line (pull down, pull up or none). The default is pull down. The value of the resistance is determined by the PGC resistor value option below.
PGC resistor value (kΩ)	Type in a resistor value from 0-50. The default value is 4.7 kΩ. If the PGC configuration is set to none, this value is ignored.
PGD Configuration	Select either none, pull up or pull down. The default is pull down. The value of the resistance is determined by the PGD resistor value option below.
PGD resistor value (kΩ)	Type in a resistor value from 0-50. The default value is 4.7 kΩ. If the PGD configuration is set to none, this value is ignored.
Program Speed	Select the speed the debugger will use to program the target as either Low, Normal or High. The default is Normal. If programming should fail, using a slower speed may solve the problem.

Erase All Before Program

Enabling this option will cause the entire device to be erased prior to programming the data from MPLAB X IDE. Any memory areas designated to be preserved will be read before the device is erased and reprogrammed on the device when the device is programmed.

Unless programming new or already erased devices, it is important to have this box checked. If not checked, the device is not erased and program code will be merged with the code already in the device.

Programming mode entry

This option designates the method the debugger will use to put the target device in programming mode. For the low-voltage method, V_PP will not exceed the V_DD supply voltage. Instead a test pattern will be used on V_PP. For the high-voltage method, a voltage in excess of 9 volts will be placed on V_PP.

Note: High voltage programming requires V_DD above 2.8V. Select low voltage programming if your target voltage is below 2.8V.

High voltage program mode entry - 2.8 to 5.0V.

Low voltage program mode entry only - 1.2 to 5.0V.

LED Brightness Setting

Select the level of brightness from 1 (darkest) to 10 (brightest).

PGC Configuration

This option determines the type of resistance that will be applied to the PGC line (pull down, pull up or none). The default is pull down. The value of the resistance is determined by the PGC resistor value option below.

PGC resistor value (kΩ)

Type in a resistor value from 0-50. The default value is 4.7 kΩ. If the PGC configuration is set to none, this value is ignored.

PGD Configuration

Select either none, pull up or pull down. The default is pull down. The value of the resistance is determined by the PGD resistor value option below.

PGD resistor value (kΩ)

Type in a resistor value from 0-50. The default value is 4.7 kΩ. If the PGD configuration is set to none, this value is ignored.

Program Speed

Select the speed the debugger will use to program the target as either Low, Normal or High. The default is Normal. If programming should fail, using a slower speed may solve the problem.
