High Frequency Clock for Receiver—When programmed as an
input, this signal provides a high frequency clock source for the
ESAI_1 receiver as an alternate to the DSP core clock. When
programmed as an output, this signal can serve as a
high-frequency sample clock (for example, for external digital to
analog converters [DACs]) or as an additional system clock.
Port E2—When the ESAI_1 is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
High Frequency Clock for Transmitter—When programmed as
an input, this signal provides a high frequency clock source for
the ESAI_1 transmitter as an alternate to the DSP core clock.
When programmed as an output, this signal can serve as a high
frequency sample clock (for example, for external DACs) or as an
additional system clock.
Port E5—When the ESAI_1 is configured as GPIO, this signal is
individually programmable as input, output, or internally
disconnected.
The default state after reset is GPIO disconnected.
Internal Pull down resistor.
This input is 5 V tolerant.
