ICTL

Interrupt control

The ICTL instruction sets all interrupts to enable or disable. Each time the ICTL instruction is executed, it is possible to set parameters like the type and validity of interrupt programs. Settings can be specified by s1_Control and s2_Condition.

s1_Control16-bit equivalent constant or 16-bit area for interrupt control setting
s2_Condition16-bit equivalent constant or 16-bit area for interrupt trigger condition setting

Parameters

Input

s1_Control (WORD, INT, UINT): Interrupt control data setting
s2_Condition (WORD, INT, UINT): Interrupt condition setting

Remarks

The number of interrupt programs available is:

16: interrupt module initiated interrupt programs (INT 0–INT 15)
8: advanced module (special modules, like positioning,...) initiated interrupt programs (INT 16–INT 23)
1: periodic interrupt program (INT 24) (Time base 0.5ms selectable for FP2/2SH, FP10SH)

Be sure to use ICTL instructions so that they are executed once at the rising edge of the ICTL trigger using the DF instruction.

Two or more ICTL instructions can have the same trigger.

NOTE

The current enable/disable status of each interrupt module initiated interrupt can be checked by monitoring the system variable sys_wInterruptMask_0_15.
The current enable/disable status of each non-interrupt module initiated interrupt can be checked by monitoring the system variable sys_wInterruptMask_16_31.
The current interrupt interval of the periodic interrupt can be checked by monitoring the system variable sys_iPeriodicInterruptInterval.
If a program is written into an interrupt task, the interrupt concerned will be enabled automatically during the initialization routine when starting the program.
With the ICTL instruction an interrupt task can be enabled or disabled by the program.
