Delta DVP-ES2/EX2/SS2/SA2/SX2/SE manual Instruction Set

3 . Instruction Set

¾Table of settings for the high-speed interrupts of the software counters and software comparators:

Counter	C232		C233	C234		C235		C236	C237
DHSCS High-speed	I010		I050	I070		I010		I020	I030
interrupt
High-speed comparator		C232~C242 share 6 software comparators
Set
Counter	C238		C239		C240		C241		C242
DHSCS High-speed	I040		I050		I060			I070	I080
interrupt
High-speed comparator		C232~C242 share 6 software comparators
Set

¾DVP-SS2/SA2/SE does not support the software high speed counter C232.

¾C253 and C254 is DVP/SE are software high speed counters. The high-speed interrupt is I030.

6.Explanations on hardware comparators DHSCS/DHSCR instruction:

¾There are 2 groups of hardware comparators provided respectively for 2 groups of hardware counters (A group and B group), and each group shares 4 comparators with individual Compare Set/Reset function.

¾When programming DHSCS and DHSCR instructions, the total of Set/Reset comparisons for both instructions can not be more than 4, otherwise syntax check error will occur.

¾Each high-speed counter interrupt occupies an associated hardware comparator, consequently the interrupt number can not be repeated. Also, I010~I040 can only be applied for group A comparators and I050~I080 for group B.
