Chapter 1 Device Overview MC9S12XE-Family
1.13
The XCLKS is an input signal which controls whether a crystal in combination with the internal loop
controlled (low power) Pierce oscillator is used or whether full swing Pierce oscillator/external clock
circuitry is used. For this device XCLKS is mapped to PE7.
The XCLKS signal selects the oscillator configuration during reset low phase while a clock quality check
is ongoing. This is the case for:
The selected oscillator configuration is frozen with the rising edge of the RESET pin in any of these above
described reset cases.
