External Interrupt Signals
Table 8 describes the external interrupt signals.

Queued Serial Peripheral Interface (QSPI)
Table 9 describes the QSPI signals.

I2C I/O Signals
Table 10 describes the I2C serial interface module signals.
1 The PLL pre-divider (CCHR+1) reset value is 1 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 less
than 10 MHz. MCF5211x devices cannot boot with PLL enabled from an external clock or
crystal oscillator with frequency greater than 10 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.
