External Interrupt Signals
Table 9 describes the external interrupt signals.
1.7
Queued Serial Peripheral Interface (QSPI)
Table 10 describes the QSPI signals.
1.8
USB On-the-Go
This device is compliant with industry standard USB 2.0 specification.
1.9
I2C I/O Signals
1 The PLL pre-divider (CCHR+1) reset value is 6 and the PLL input reference range is 2–10 MHz,
so in order to boot with the PLL enabled, the external clock or crystal frequency needs to be
greater than 12 MHz. MCF5222x devices cannot boot with PLL enabled from an external clock
or crystal oscillator with frequency less than 12 MHz. This constraint does not apply to booting
with PLL disabled.
2 Cannot boot from the Internal 8 MHz Relaxation oscillator with the PLL enabled. Refer Note1.
Thus this mode has been removed from the table.

QSPI Serial Clock
QSPI_CLK
Provides the serial clock from the QSPI. The polarity and phase of
QSPI_CLK are programmable.

Serial Clock
SCLn
Open-drain clock signal for the for the I2C interface. When the bus is
In master mode, this clock is driven by the I2C module; when the bus
is in slave mode, this clock becomes the clock input.
