4. 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).

Note:
Absolute 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 Absolute Maximum Ratings 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.
