ADDRESS 4 On the CYCTM 10 the second 9513 counter timer chip s address is fixed at the board s base address 4 If the board were configured at 300H 768 Decimal then the second 9513 would reside at 304h 772 Decimal No switches need to be set 4 REGISTER ARCHITECTURE 4 1 CONTROL amp DATA REGISTERS The CYCTM 10 is composed of 2 AM9513 counter timer chips The CYCTM 05 contains one 9513 Each 9513 contains five counters of 16 bits each Associated with each counter are an input source a count register a load register a hold register an output and a gate The 9513 is extremely flexible and this flexibility can make it a challenge to program the chip directly Unlike an Intel 8254 which has a single source single gate and unique I O address for each counter the 9513 is fully programmable and any counter may be internally con nected to any gate and receive it s counts from a number of sources In addition each counter does not have a unique I O address The 9513 takes only two address per chip one of which is a data path to the counter s load and hold registers There is no 9513 register information in this manual Those wishing to know more about the AM9513 and its programming should request the manual from our technical support group As of this writing there is no charge for the manual However we suggest that you use the Universal Library rather than resort to pro gramming the 9513 directly It is difficult to program
