	UNIVERSAL DEFS -- TM03 specific macro definitions for RDREG
	SUBTTL	N. B. Mahoney/NBM


;This file contains the TM03 specific macro definitions for RDREG
;to interpret the TMO3 massbus registers.  The format of the macros
;is decribed when each macro is defined.

	SUBTTL	Assembly parameters and drive type register definitions


;The following definition controls whether RDREG will ask for the
;DATAO/DATAI drive select field in addition to the RH20 device
;code.  For those devices that are always in massbus slot 0 (the
;DX20 for example), set FTDSEL to a 0 and RDREG will always use
;a drive select field of zero.  For those devices that do require
;a drive select code, set FTDSEL to -1 and RDREG will ask for and
;use the drive select value specified by the user.

FTDSEL==-1			;Need drive select for TM03's




;The following macro defines the drive type register values for those
;devices that we can interpret.  The arguments to the DTRTYP macro
;are as follows:
;
;	1 - Octal value of drive type (right 9 bits)
;	2 - Corresponding mnemonic for this drive type (this mnemonic
;	    is used in the second level macro definitions below)

;The following macro defines the registers that we want to read and
;interpret in the device.  The arguments to the XX macro are as
;follows:
;
;	1 - Massbus register number (register select field)
;	2 - Mnemonic for the register
;
;Note that the CONI definition MUST be first.  RDREG depends on this
;and will work incorrectly if it is not.

	SUBTTL	Second level massbus register definitions


;The following macros define the bits and fields in each of the
;massbus registers that we want to interpret.  For each massbus
;register mnemonic that we defined in the first level macro definition
;above, we define a macro with the same name here that gives the
;bit and field definitions for that register.  The arguments to
;the FIELDS macro are as follows:
;
;	1 - The bit mask of the bit or field in the 36 bit word
;	2 - The text associated with the bit or field
;	3 - One of BIT, VAL, or NVAL to indicate that this entity is a
;	    bit, a field containing a positive number, or a field containing
;	    a negative number, repectively.  RDREG only interprets BIT values
;	    if the bit is on.  VAL values are always printed as a field. NVAL
;	    values are first negated and then always printed as a field.
;	4 - Either ALL or one of the drive type mnemonics defined by
;	    the DRVTYP macro above.  ALL values are interpreted for
;	    all of the legal drive types. Values that are given with
;	    a specific drive type mnemonic are only interpreted if the
;	    device is of that drive type.
