Introducing HSL 25
1.4.6 I/O refreshing rate of an HSL system
The scan time unit for one slave index is set in 3/6/12 Mbps trans-
mission rate. Once the maximum slave address is set, the polling
cycle time of the HSL system is using the following formula:
Polling cycle time = maximum-address-of-slave * scan time unit
Table 1-5: Polling cycle time of HSL (Full Duplex Mode)
Note: Regardless of the transmission rate you select, the minimum
polling cycle time is 3×scan time unit, even when the maxi-
mum address is less than 3. Refer to Appendix A.
