1.1 ! root 1: .TH PAL 10.1 UCDS ! 2: .SH NAME ! 3: pal \- data preparation program for PAL's and PLA's ! 4: .SH SYNOPSIS ! 5: .B pal ! 6: [ ! 7: .BI - option ! 8: ] [ ! 9: .I type ! 10: [ ! 11: .I filename ! 12: ] ] ! 13: .SH DESCRIPTION ! 14: .I Pal ! 15: reads data from the standard input or ! 16: .I filename ! 17: in the form of ! 18: .IR minterm (10.5) ! 19: and writes on the standard output data suitable ! 20: for ! 21: .IR prom (10.1) ! 22: driving a PRO LOG programmer with a MMI PAL adapter. ! 23: .PP ! 24: The options are: ! 25: .TP ! 26: .B -x ! 27: Produce a table filled with '\-' (fuse blown) or 'X' ! 28: (fuse present) for checking by human being. ! 29: .TP ! 30: .B -d ! 31: Produce output suitable for use by ! 32: .IR drom (10.1) ! 33: driving a DATA I/O programmer with a LogicPak. ! 34: .PP ! 35: .I Pal ! 36: has internal tables that describe the fuse layout ! 37: and addressing inside the chips. The ! 38: .I type ! 39: flag on the command line is used to address the correct tables. ! 40: .I type ! 41: means the pal type, for example, "AM22V10". ! 42: .PP ! 43: The numeric symbol of a term that corresponds to the output ! 44: enable of a pin is 100 + pin_number by convention. Just to be strange, ! 45: the convention for the 22V10 is: 200 + pin_number for polarity, ! 46: 300 + pin_number for architecture fuses and pins 25 and 26 are ! 47: asynchronous reset and synchronous preset respectively. ! 48: .PP ! 49: The pals with X in their name use an additional convention. ! 50: Since ! 51: .IR quine (10.1) ! 52: can only handle and-or logic, and the X pals have two ! 53: different sets of and-or logic driving the two inputs of an xor gate, ! 54: those two terms are number 200 + output pin number and 300 + ditto. ! 55: .SH SEE ALSO ! 56: .IR minterm (10.5), ! 57: .IR prom (10.1), ! 58: .IR drom (10.1), ! 59: .IR eprom (10.1) ! 60: .SH BUGS ! 61: Unfortunately, the devices are compiled in. Case is important for device ! 62: names. ! 63:
