5. This value as an example is calculated when the conditions described in the “Conditions” column are met.
Refer to Note 4 above to calculate the maximum transfer rate under conditions of the customer.
<R>
6. The smaller maximum transfer rate derived by using fMCK/6 or the following expression is the valid
maximum transfer rate.

9. This value as an example is calculated when the conditions described in the “Conditions” column are met.
Refer to Note 8 above to calculate the maximum transfer rate under conditions of the customer.
Caution Select the TTL input buffer for the RxDq pin and the N-ch open drain output (VDD tolerance) mode for
the TxDq pin by using port input mode register g (PIMg) and port output mode register g (POMg).
For VIH and VIL, see the DC characteristics with TTL input buffer selected.
