Turbo PMAC Global I-Variables 93
In this mode, bits 3 through 7 of Ixx10 match the settings of DIP switches SW1-1 through SW1-5,
respectively, of the Acc-8D Option 9 Yaskawa converter board.
A Closed switch represents a bit value of 0; an OPEN switch represents a bit value of 1. Bits 0 through 2,
and bits 8 though 23, of Ixx10 are always set to 0 in this mode.
The following table shows the Multiplexer Port addresses that can be used and the matching values of
Ixx10. Note that address 0 uses an Ixx10 value of $000100, because Ixx10=0 disables the absolute
position read function.

MACRO Absolute Position Read: If Ixx95 contains a value from $720000 to $740000, or from
$F20000 to $F40000, the value specified in Ixx10 is a MACRO node number, and Turbo PMAC will
obtain the absolute power-on position through the MACRO ring. Ixx95 specifies what type of position
data is used, and whether it is treated as a signed or unsigned value.
The MACRO node number is specified in the last two hex digits of Ixx10. The second-to-last digit
specifies the MACRO IC number 0 to 3 (1, 2, and 3 exist only on Ultralite versions of the Turbo PMAC2,
or a UMAC Turbo with Acc-5E). Note that the MACRO IC number on the Turbo PMAC does not
necessarily match the ring master number for that IC, although it often will. The last digit specifies the
MACRO node number 0 to 15 (0 to F hex) in that IC. This function is only supported in nodes 0, 1, 4, 5,
8, 9, 12 (C), and 13 (D).
The following table shows the required values of Ixx10 for all of the MACRO nodes that can be used.
Note that MACRO IC 0 Node 0 uses an Ixx10 value of $000100, because Ixx10=0 disables the absolute
position read function.
