kv10.def

# 'uas' configuration file for the KV10 uengine
#
# The contents consist of a number of lines containing tokens; the order
# of the lines, and the tokens that each contains, are fixed.
#
# Tokens are separated by white space (either space or tab - extra white
# space is ignored); blank lines are ignored, and comment lines _start_ with
# a '#', ';', or '/'.
#
# Numeric items are either octal (leading "0"), decimal or hexadecimal
# (with a leading "0x"; uppercase A-F only).

# The first line _must_ contain the uword width, and uROM size

64 2048

# The second line _must_ contain the format strings used for printing addresses,
# uinsts, and literals

0%04o 0%022llo 0%04o

# Next comes a block of lines containing the field definitions: it starts with
# a line containing the number of field definitions, then the definitions,
# one field per line, and finally a line with only a '.' to mark the end of
# the table. (The number, and terminator, are there as cross-checks.)
#
# Each field definition line contains: the field name (a string), the
# default value for that field (a string; 'none' if none), the location of
# the start bit for the field, the number of bits in the field, and two
# control tokens (strings, here, using names defined in uas.c) which are
# used in dis-assembling uinsts when producing a ucode listing.
#
# The first token says what form the field takes (a bit string, an ordinal,
# or a literal); the second token says how the literal field is used (if
# it is used with this field). 'none' is an acceptable value for the
# second token, but not the first. The literal use token also indicates
# whether all values for this field use the literal, or only some;
# a leading 'v' in the token indicates the latter.
#
# The start bits for each field are given, as well as the field width, as
# a cross-check - it does make a little work if a field is inserted in the
# middle of the uword, but it was felt that this price was worth paying
# for the benefit of being able to do a consistency check.

# Finally, a block of lines containing the field value definitions: like
# the previous section, it starts with a line containing the number of
# value definitions, then the definitions themselves, one per line, and
# finally a line with only a '.' to mark the end of the table.
#
# Each value definition line contains: the value name (a string), the
# field that value belongs to (another string), the numeric value of
# that value (relative to the field - 'uas' will convert it to the
# correct value to go in the uword), and one control token (a string,
# here) used in dis-assembling uinsts.
#
# That token says if the literal field is used for this value (if it is
# used with some, but not all, values of that field). 'yes' and 'no' are
# the acceptable values for this token.
