PP84 programmer software general usage notes
Steve Marchant, CCC, Nottingham university

PP84 with no parameters will reset the in-system PIC

Other command line options via 'pp84 --help' 

PP84 with the name of an 8-bit HEX file will read in the file,
 validate it, report its 16 bit code check-sum, then proceed
 to program the embedded data into the attached PIC16C84 device.
 
 Data words at locations below $400 are programmed into code memory.
 
 Data nibbles at locations $2000-2004 are programmed into ID memory.
 
 Any Data item at location $2007 is programmed into the Config word. 
 
 Note that code protection is delayed 'til the end of programming.
 
 Data bytes at locations $2100-$213F are programmed into EE data memory.
 
 Programming errors are displayed to the screen, but programming continues.

 Upto 5 errors are tollerated before aborting the job.

 A code protected device will automatically be bulk erased.

 Only the locations specified the HEX file are programmed & verified.

 A location which already contains the correct data will not be programmed.

 The software will not start unless a PROG84 adapter is connected, unless
 forced by a command line option.

 PP84 scans for PROG84 hardware at 3 common LPT port addresses.

 An overall verify pass is executed after the programming sequence.


To Do List:

* Option to override OSC settings in config word.
