Support summary
ICSP Connection
All VSS and VDD pins must be connected. Even if one of these pins is not connected, programming may fail.
LVP Programming
Low-Voltage Programming (LVP) can only be used for these PIC devices if the LVP configuration bit is enabled. Fresh (unprogrammed) devices have LVP bit set and therefore they can be programmed. It is impossible to disable LVP bit during LVP programming, but if the device has been previously programmed with HVP programmer, the LVP bit may have been disabled.
When brown-out is enabled with BOREN configuration bit, LVP is only possible when the VDD voltage is above the brown-out threshold.
These limitations may be avoided with High-Voltage Programming (HVP). NSDSP-2 can generate high voltage for HVP internally. NSDSP-1 cannot, therefore NSDSP-1 requires NSHVX or an external circuit for HVP.
HVP Programming
NSDSP-2 can program PIC18F8723 with HVP.
With NSDSP-1, HVP programming is possible, but only with NSHVX High Voltage Extension or an external HVP circuit.
Debugging
NSDSP firmware contains all the necessary provisions for debugging PIC18F8723 and may be debugged when debugging software becomes available.
PIC18F8723 uses ordered halting, has 3 hardware breakpoints.
Debugger requires 768 bytes of ROM and 16 bytes of RAM.
