Note: Among the 6 pairs of interruption No. (I001, I010), (I101, I020), (I201, I030), (I301, I040), (I401, I050), (I501, I060), only 1 No.
in the pair is allowed to be used in the program. If you use both No. in the pair and write them into the program, there may be
syntax errors occurring.
EH/EH2/SV series MPU:
N Master control loop N0 ~ N7, 8 points
Control point of master
control loop
P For CJ, CALL instructions P0 ~ P255, 256 points
Position pointer of CJ,

External interruption
I00□(X0), I10□(X1), I20□(X2), I30□(X3), I40□
(X4), I50□(X5), 6 points
(□ = 1, rising-edge trigger
, □ = 0,
falling-edge trigger )
Timed interruption
I6□□, I7□□, 2 points (□□ = 1 ~ 99, time
base = 1ms)
I8□□, 1 point (□□ = 1 ~ 99, time base =
0.1ms)
High-speed counter

I010, I020, I030, I040, I050, I060, 6 points
Pulse interruption I110, I120, I130, I140, 4 points
Communication

triggered interruption
I180, 1 point
Position pointer of
interruption subroutine
Note: Input point X as a high-speed counter cannot be used as an external interruption signal. For example, if C251 occupies X0,
X1, X2 and X3, the external input interruption No. I00□(X0), I10□(X1), I20□(X2), and I30□(X3) cannot be used.
Pointer N: Used with MC and MCR instructions. MC is the master control start instruction. When MC instruction is
executer, the instructions between MC and MCR will still be executed normally. See Chapter 3 explanations on MC
and MCR instructions for more details.
Pointer P: Used with API 00 CJ, API 01 CALL and API 02 SRET. See Chapter 6 explanations on CJ, CALL and SRET
instructions for more details.
CJ Conditional Jump:
X2
Y2
X1
P1 CJ
X0
Y1
P**
0
P1 N
When X0 = On, the program will jump from
address 0 to N (designated label P1) and keep
on the execution. The addresses in the middle
will be ignored.
When X0 = Off, the program will execute from
address 0 and keep on executing. At this time,
CJ instruction will not be executed.
