GPIO. Signals GPIO[31–0], when used as GPIO signals, that is, when the alternate multiplexed special functions are
not selected.
When used as a GPI, the input should be driven until it is acknowledged by the device; the GPIO input status is read
from a register.
EE port. Signals EE0, EE1, EE2_0, EE2_1, EE2_2, and EE2_3.
Boot function. Signal STOP_BS.
I
Interrupt inputs. Signals IRQ[15–0] and NMI.
Interrupt outputs. Signals INT_OUT and NMI_OUT (pulse width is 10 ns).
