Data Movement Instructions Section 5-17
Description When the execution condition is OFF, BSET(71) is not executed. When the
execution condition is ON, BSET(71) copies the content of S to all words from
St through E.
BSET(71) can be used to change timer/counter PV. (This cannot be done with
MOV(21) or MVN(22).) BSET(71) can also be used to clear sections of a data
area, i.e., the DM area, to prepare for executing other instructions. It can also
be used to clear words by transferring all zeros.
Flags ER: St and E are not in the same data area or St is greater than E.
Indirectly addressed DM word is non-existent. (Content of *DM word
is not BCD, or the DM area boundary has been exceeded.)
Example The following example shows how to use BSET(71) to copy a constant
(#0000) to a block of the DM area (DM 0000 to DM 0500) when IR 00000 is
ON.
5-17-5 DATA EXCHANGE – XCHG(73)
Limitations DM 6144 to DM 6655 cannot be used for E1 or E2.
Description When the execution condition is OFF, XCHG(73) is not executed. When the
execution condition is ON, XCHG(73) exchanges the content of E1 and E2.
If you want to exchange content of blocks whose size is greater than 1 word,
use work words as an intermediate buffer to hold one of the blocks using
XFER(70) three times.
