Notes:
1.
Refer to Table 27 for a definition of the APBCLK period.
2.
Direction of the EVNT signal is configured through the GPIO and Event port registers.
3.
Refer to the signal chapter in the MSC711x Reference Manual for details on EVNT pin functionality.

2.
Direction of the GPIO signal is configured through the GPIO port registers.
3.
Refer to Section 1.5 for details on GPIO pin functionality.
4.
GPI data is synchronized to the APBCLK internally and the minimum listed is the capability of the hardware to capture data
into a register when the GPADR is read. The specification is not tested due to the asynchronous nature of the input and
dependence on the state of the DSP core. It is guaranteed by design.
5.
The output signals cannot toggle faster than 75 MHz.
6.
Level-sensitive interrupts should be held low until the system determines (via the service routine) that the interrupt is
acknowledged.
