Electrical Characteristics
The letter x in equations presented in this chapter represents the cycle period of the fsys clock selected
through the programming of the SYSCR1.SYSCK bit. The fsys clock may be derived from either the high-
speed or low-speed crystal oscillator. The programming of the clock gear function also affects the fsys
frequency. All relevant values in this chapter are calculated with the high-speed (fc) system clock
(SYSCR1.SYSCK = 0) and a clock gear factor of 1/fc (SYSCR1.GEAR[1:0] = 00).

Maximum ratings are limiting values of operating and environmental conditions which
should not be exceeded under the worst possible conditions. The equipment manufacturer
should design so that no maximum rating value is exceeded with respect to current,
voltage, power dissipation, temperature, etc. Exposure to conditions beyond those listed
above may cause permanent damage to the device or affect device reliability, which could
increase potential risks of personal injury due to IC blowup and/or burning.
