When M0 = ON, M1280 = ON. X0 external interrupt will be triggered by falling-edge pulse.
Users do not have to change I101 to I000.

If external interrupts are applied on input points for Reset, the interrupt instructions have the
priority in using the input points. In addition, the ELC will move the current data in the
counters to the associated data registers below then reset the counters.

2. Function:
a) When X0 (counter input) and X1 (external Interrupt) correspondingly work together with C243,
and I100/I101, the ELC will move the count value to D1241 and D1240.
b) When X0 (counter input) and X4 (external Interrupt) correspondingly work together with C246,
C248, C252 and I400/I401, the ELC will move the count value to D1241 and D1240
c) When X2 (counter input) and X3 (external Interrupt) correspondingly work together with C244,
and I300/I301, the ELC will move the count value to D1243 and D1242.
d) When X2 (counter input) and X5 (external Interrupt) correspondingly work together with C250,
C254 and I500/I501, the ELC will move the count value to D1243 and D1242.

When external interrupt (X1, I101) occurs during counting process of C243, the count value in
C243 will be stored in (D1241, D1240) and C243 is reset. After this, the interrupt subroutine I101
will be executed
