z When count control "EN" = 1 or "EN↑" ( P instruction) has a transition from 0 to 1, then among the 16L bits
of the Ms matrix, this instruction will count the total amount of bits with a status of 1 (when input "1/0" = 1)
or the total amount of bits with a status of 0 (when input "1/0" = 0). The results of the counting will be stored
into the register specified by D. If the value of these amounts is 0, then the Result-is-0 flag "D = 0" will be set
to 1.

z The program at left sets X1 first as 0 (to count bits with
status of 0) and then as 1 (to count bits with status of 1)
and let the signal X0 has a transition from 0
→1 for both
case, the execution results are shown at right in the
