PIC18F2XXX/4XXX family devices in all package
types.
2.1
In High-Voltage ICSP mode, PIC18F2XXX/4XXX
family devices require two programmable power sup-
plies: one for V
supplies should have a minimum resolution of 0.25V.
Refer to
Requirements for Program/Verify Test Mode”
additional hardware parameters.
2.1.1
In Low-Voltage ICSP mode, PIC18F2XXX/4XXX
family devices can be programmed using a V
source in the operating range. The MCLR/V
does not have to be brought to a different voltage, but
can instead be left at the normal operating voltage.
Refer to
Requirements for Program/Verify Test Mode”
additional hardware parameters.
