PD6 — IRQ2
The port pin PD6 is configured as IRQ2 by setting the IRQ2E bit in the MCR. The external interrupt
IRQ2 behaves similar to IRQ except it is edge-triggered only.
See Section 5.2.2.2 for details on the external interrupt IRQ2.

Programmable Current Drive
All I/O ports, when programmed as outputs, can source or sink a current of 10mA for driving LEDs
directly. By setting the PIL bit in the Port Option Register (at $0A), PB5-PB7 can be programmed
to a low-current mode that source or sink only a current of 2mA when programmed as output. This
allows a direct drive to low current LEDs.
Note:
Although the ports each has high current drive capability, designs should limit the total
port currents to not more than 100mA.
