TML Interrupts – Related TML Instructions and Data

Parameters

INTTABLE Pointer to the start address of the interrupt table

TMLINTPER

Time period for the periodic time interrupt Int10. Measured in time_units

Instructions

EINT Globally enables the TML interrupts. Sets ICR.15 = 1

DINT Globally disables the TML interrupts. Sets ICR.15 = 0

SRB ICR, ANDm, ORm

Individually enable/disable TML interrupts, by setting/resetting bits from ICR register according with AND mask ANDm and OR mask ORm

SRB ISR, ANDm, 0;

Reset interrupt flags in the ISR register according with AND mask ANDm

RETI Return from a TML interrupt service routine

Programming Example

Set TML Int10 to generate a time interrupt at each 0.5s. In the ISR, switch the status of output #25/Ready to signal that the drive/motor is in standby. Leave the other TML interrupts with their default ISR.

BEGIN; // TML program start

INTTABLE = InterruptTable; // set start address for the new interrupt table

ENDINIT; // end of initialization

...

int Ready_status; // Define integer variable Ready_status

Ready_status = 0; // initialize Ready_status

TMLINTPER = 500; //Set a time interrupt at every 0.5[s]

SRB ICR, 0x8FFF, 0x0400; // Set ICR.10 to enable Int10

...

END; // end of the main section

InterruptTable: // start of the interrupt table
