† Characteristics are over recommended operating conditions unless otherwise stated.
‡ Typical figures are at 25°C and are for design aid only: not guaranteed and not subject to production testing.
*Note 1: A delay of 100 microseconds must be applied before the first microprocessor access is performed after the RESET pin is set high.
*Note 2: High Impedance is measured by pulling to the appropriate rail with R
