HSL Function Library 93

Type 3: Generates hardware interrupt when any DI data transi-

tions are detected and when the scan cycle is completed. When

interrupt occurrs, the scan pauses until the driver resets the state.

Figure 5-3: Type 3

Caution: Scanning is paused while user choice the type3 of renewal

type. This pause time depends on the user system perfor-

mance. Consequently, when using type3, constancy(always

keeping scan cycle constant) will not be maintained between

scans.

HSL_D_set_int_renewal_bit (7853/54 only):

Sets the Di data bits of specified modules that you want to monitor.

HSL_D_set_int_control (7853/54 only):

Enables or disables the DI interrupt.

HSL_D_wait_di_interrupt (7853/54 only):

Waits for the specific interrupt when you enable the Interrupt func-

tion by HSL_D_set_int_control() and set the renewal type and

data bits on specified slave DI modules by

HSL_D_set_int_renewal_bit(), HSL_D_set_int_renewal_type().

When this function is running, the process never stops even if trig-

gered or the function timed out. The following codes illustrate this

function.

I16 ret;

HSL_D_set_int_renewal_type(1, 0, 1);

// slave id = 1, monitor the states of bit 0 and

bit 1

HSL_D_set_int_renewal_bit(1, 0, 1, 0x003);

HSL_D_set_int_control(1, 0, 1); //enable
