It can also be used for registers in the 3U-format Acc-3E1 (for 3U Turbo Stack systems) and Acc-14E
(for UMAC Turbo systems) boards. In this case, the last hex digit of Ixx95 must be set to a non-zero
value to specify the byte-wide bus of these boards. The following tables show Ixx10 values for these
boards.

SW1-5 & 6 must be ON (0). ON means CLOSED; OFF means OPEN.
The final digit, represented by an x in both of these tables, can take a value of 0 to 5, depending on which
I/O point on the board is used for the least significant bit (LSB):

Acc-28 A/D Converter Read: If Ixx95 is set to $310000 or $B10000, the address specified by Ixx10 is a
Turbo PMAC ‘Y’ memory-I/O address, and Turbo PMAC will read the data in the high 16 bits of that
address as the absolute position (the LSB – one count – is in bit 8). This format is intended for the Acc-
28A and Acc-28B A/D converters.
The following table shows the settings of Ixx10 for these registers.
