
The number of bits which are 1 in S is stored in D .

S : Source device; D : Destination device

If the bits in S are 0, a zero flag will be ON.

If the 32-bit instruction is used, D will occupy two registers.

If KnM/KnS is used, it is suggested that M device numbers/S device
numbers should start from a number which is a multiple of 16 in the
decimal numeral system, e.g. K1M0 and K4M16 (decimal numeral
system).

SM1064 is the zero flag in an Ox motion subroutine, and SM968 is the
zero flag in O100.
