Signal Description
HCKR_1
Input or output
GPIO
disconnected
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 (e.g., for external
digital to analog converters [DACs]) or as an additional
system clock.
PE2
Input, output, or
disconnected
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.
HCKT_1
Input or output
GPIO
disconnected
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 (e.g., for
external DACs) or as an additional system clock.
PE5
Input, output, or
disconnected
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.
