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.
