b. To determine the register in the slot where the bus

error occurred, take the slot number you decode in

THIS RACK SLOT #" and decode the least significant

16 bits according to the type of module found in the

slot:

Any Local I/O Module*

The bit number being accessed may be determined from word

bit#=BYTEBIT#+(8*b)

If BYTE BIT # and 8*b = 0, address may have been accessed

as a word (integer) or bit 0 of byte 0.

* The hexadecimal number represents the Multibus

address of the error. Therefore, the standard Reliance

register number for any type of module can be decoded

from this figure and the figure in part a. For more specific

information, e.g., drop number, use the applicable figures

that follow.
