Output Signals:
Input Signals:
GPIO. Signals GPIO[31–0], when used as GPIO signals, that is, when the alternate multiplexed special functions are
not selected.
EE port. Signals EE0, EE1.
Boot function. Signal STOP_BS.
I
Interrupt inputs. Signals IRQ[15–0] and NMI.
Interrupt outputs. Signals INT_OUT/CP_TX_INT and NMI_OUT/CP_RX_INT (minimum pulse width is 32 ns).

C interface. Signals I2C_SCL and I2C_SDA.
Asynchronous Signal Timing
When used as a general purpose input (GPI), the input signal should be driven until it is
acknowledged by the MSC8157 device, that is, when the expected input value is read from
the GPIO data register.
