2.4.2.7
If the pin is used as an output this register turns off the active high drive. This allows wired-or type
connections of outputs.
2.4.2.8
If the pin is used as an interrupt input this register serves as a mask to the interrupt flag to enable/disable
the interrupt.
2.4.2.9
If the pin is used as an interrupt input this register holds the interrupt flag after a valid pin event.
2.4.2.10
These registers allow software re-configuration of the pinouts of the different package options for specific
peripherals:
2.4.3
2.4.3.1
The BKGD pin is associated with the BDM module.
During reset, the BKGD pin is used as MODC input.
2.4.3.2
Port A pins PA[7:0] and Port B pins PB[7:0] can be used for general-purpose I/O.
2.4.3.3
Port E is associated with the free-running clock outputs ECLK, ECLKX2 and interrupt inputs IRQ and
XIRQ.
Port E pins PE[7:2] can be used for either general-purpose I/O or with the alternative functions.
Port E pin PE[7] an be used for either general-purpose I/O or as the free-running clock ECLKX2 output
running at the core clock rate.
Port E pin PE[4] an be used for either general-purpose I/O or as the free-running clock ECLK output
running at the bus clock rate or at the programmed divided clock rate.
