z When write control "EN" = 1 or "EN↑" ( P instruction) has a
transition from 0 to 1, the status of the write-in bit "INB" will be
written into the bit Mdpr pointed by pointer Pr within matrix Md.
Before the write-in takes place, the status of pointer clear "CLR"
will be checked. If "CLR" is 1, then Pr will be cleared to 0 before
the write-in action. After the write-in action has been completed,
the Pr value will be checked again. If the Pr value has already
reached 16L-1 (last bit), then the write-to-end flag will be set to
1. If the Pr value is less than 16L-1 and "INC" is 1, then the
pointer will increased by 1. Besides this, pointer clear "CLR" can
execute independently, and is not affected by other input.

z The effective range of Pr is 0 to 16L-1. Beyond this range, the pointer error flag "ERR" will be set to 1, and

z In the program at left, pointer will be increased each time
execution (because "INC" is 1). As shown in the diagram
below, when X0 has a transition from 0→1, the status of
INB (X1) will be written into the Mdpr (Md
78
) position, and
pointer Pr will increased by 1 (changing to 79). In this
case, although Pr is pointing to the end, it has not yet
been written into Md
79
, so "END" flag is still 0. Only the
next attempt to write to Md
79
will set “END” to 1.
