According to SMARC
CN92
fourteen general purpose I/O pins at 1.8V electrical level: GPIO0 to GPIO13.
FuSa Interface
Each of these can be configured as an input or output pin.
GPIO7 to GPIO13 are dedicated GPIOs, while the other seven GPIOs are multiplexed
pins supporting functions like Camera Power Enable, Camera Reset, Tachometer input,
PWM output etc. All these GPIOs, together with others signals from card edge
connector, are made available to a dual row, 28 pin, P2.54mm standard pin header,
type ADIMPEX p/n LE008228-R, with the pinout shown in the table on the left.
FUSA_OKNOK0
FUSA_OKNOK1
FUSA_ALERT#
FUSA_SPIS_CS#
This connector can be also used to provide functional safety functions for FuSa
applications through signals listed in left table. Please be aware that FuSa functionality
FUSA_SPIS_SCLK
can be obtained only in case that it is supported by the SMARC
FUSA_SPIS_MISO
CSM-B79 carrier board. Please refer to specific SMARC
FUSA_SPIS_MOSI signal description related to this section (FuSa interface).
