ICS TRIPLEX T8921 Channel isolation module

If the "N" (non-aligned) option has been selected, then the data is searched for on a byte-by-byte basis, rather than by words or longwords, regardless of the size of data. This is useful if a word (or longword) pattern is being searched for, but is not expected to lie on a word (or longword) boundary.If a match is found, then the address of the first byte of the match is output along with the memory contents. If a mask was in use, then the actual data at the memory location is displayed, rather than the data with the mask applied. Mode 3 - DATA VERIFICATION -- If the "V" (verify) option has been selected, then displaying of addresses and data is done only when the memory contents do NOT match the user-specified pattern. Otherwise this mode is identical to Mode 2.

For all three modes

 information on matches is output to the screen in a four-column format. If more than 24 lines of matches are found, then output is inhibited to prevent the first match from rolling off the screen. A message is printed at the bottom of the screen indicating that there is more to display. To resume output, you should simply press any character key. To cancel the output and exit the command, you should press the BREAK key. If a match is found (or, in the case of Mode 3, a mismatch) with a series of bytes of memory whose beginning is within the range but whose end is outside of the range, then that match is output and a message is output stating that the last match does not lie entirely within the range. You may search non-contiguous memory with this command without causing a Bus Error.

The BV command compares 

the specified range of memory against a data pattern. If an increment is specified, then data is incremented by this value following each comparison, otherwise data remains a constant value. You may accomplish a decrementing pattern by entering a negative increment. The data you enter is right-justified in either a byte, word, or longword field (as specified by the option selected). If the user-entered data or increment (if specified) does not fit into the data field size, then leading bits are truncated to make them fit. If truncation occurs, then a message is printed stating the data pattern and, if applicable, the increment value actually used. If the range is specified using a count, then the count is assumed to be in terms of the data size.
