Signal Description
2.19
The MCF5253 is fitted with an on-chip USB controller.
2.19.1
There is an integrated on-chip USB PHY. Pins are described in
2.20
There is a real-time clock integrated in the device. Pins are described in
2.21
The XTRIM/TXD2/GPIO0 output produces a pulse-density modulated phase/frequency difference signal
to be used after low-pass filtering to control varicap-voltage to control crystal oscillation frequency. This
will lock the crystal to the incoming digital audio signal.
2.22
The MCLK1/GPIO11 and QSPI_CS2/MCLK2/GPIO24 can serve as DAC clock outputs. When
programmed as DAC clock outputs, these signals are directly derived from the crystal oscillator or clock
Input (CRIN).
2.23
These signals interface with external I/O to provide processor debug and status signals.
