15 0 Switching Characteristics
Note 1 The addition of wait states affects the count of deserialized bytes and is limited to a number of bus clock cycles depending on the bus clock and network
rates The allowable wait states are found in the table below (Assumes 10 Mbit sec data rate )
Table assumes 10 MHz network clock
