A.10 External Oscillator (XOSC) Characteristics
Freescale Semiconductor
Data in Typical column was characterized at 3.0 V, 25°C or is typical recommended value.
When MCG is configured for FEE or FBE mode, input clock source must be divisible using RDIV to within the range of 31.25
kHz to 39.0625 kHz.
When MCG is configured for PEE or PBE mode, input clock source must be divisible using RDIV to within the range of 1 MHz
to 2 MHz.
This parameter is characterized and not tested on each device. Proper PC board layout procedures must be followed to achieve
specifications. This data varies based on crystal manufacturer and board design. The crystal should be characterized by the
crystal manufacturer.
