Asynchronous Signal Timing
The following interfaces use the specified asynchronous signals:
GPIO
. Signals GPIO[31–0], when used as GPIO signals, that is, when the alternate multiplexed special functions are
not selected.
Note:
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
2
C interface
. Signals I2C_SCL and I2C_SDA.
Interrupt inputs
. Signals IRQ[15–0] and NMI.
Interrupt outputs
. Signals INT_OUT and NMI_OUT (pulse width is 10 ns).
Figure 38
shows the behavior of the asynchronous signals.
