6. During the execution of an interrupt routine, an immediate I/O instruction can be performed by
using the REF instruction.
Points to note:
1. ELC-PB. ELCB-PB models interrupt pointers (I):
a) External interrupts: (I001, X0), (I101, X1), (I201, X2), (I301, X3) 4 points.
b) Time interrupts: I6
□□
, 1 point (
□□＝
10~99, time base=1ms)
c) Communication interrupt for specific characters received (I150)
d) Flags:
Flag Function
M1050 External interrupt, I 001 masked
M1051 External interrupt, I 101 masked
M1052 External interrupt, I 201 masked
M1053 External interrupt, I 301 masked
M1056
Disable time interrupt I6

2. ELC-PC/PA/PH models Interrupt pointers (I):
a) External interrupts: (I001, X0), (I101, X1), (I201, X2), (I301, X3), (I401, X4), (I501, X5) 6 points.
b) Time interrupts: I6
□□
, I7
□□
2 points. (
□□＝
1~99ms, time base=1ms)
c) High-speed counter interrupts: I010, I020, I030, I040, I050, I060 6 points. (used with DHSCS
instruction)
d) Communication interrupt for specific characters received (I150)
e) The priority of interrupt pointer I: high-speed counter interrupt, external interrupt, time interrupt
and communication interrupt for specific characters received
f) Among the following 6 interrupts, (I001, I010), (I101, I020), (I201, I030), (I301, I040), (I401,
I050), (I501, I060), the program allows the user to use only one of the two numbers in a pair. If
the user uses the two numbers in the pair, syntax check errors may occur when the program is
written to the ELC controller.
g) Flags:
Flag Function
M1050 External interrupt, I 001 masked
M1051 External interrupt, I 101 masked
M1052 External interrupt, I 201 masked
M1053 External interrupt, I 301 masked
M1054 External interrupt, I 401 masked
M1055 External interrupt, I 501 masked
M1056 Timer interrupt, I6

M1057
Timer interrupt, I7
