Notes: 1. Determined by the SA1 and SA0 bits in the system control register 2 (SYSCR2).
2. These characteristics are given as ranges between minimum and maximum values in
order to account for factors such as temperature, power supply voltage, and variation
among production lots. When designing systems, make sure to give due consideration
to the SPEC range. Please contact a Renesas sales or support representative for
actual performance data on the product.
