Chapter 1 Device Overview MC9S12XD-Family
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 reset.
The pin can be configured to drive the internal system clock ECLKX2.

PE6 is a general-purpose input or output pin. It is used as a MCU operating mode select pin during reset.
The state of this pin is latched to the MODB bit at the rising edge of RESET. This pin is an input with a
