Serial Flash Interface (Pins #17, #1, #3, #2, #57, #58 and #56)
The ALT1210MOD-VZ-01 module has an internal small flash memory to store the
calibration and configuration files. The actual firmware is loaded from an external
Flash located on the application board. The external and interna flash devices share
the same interface bus, but have separated SF_nCSx lines. The boot is done from
the external Flash controlled by SF_nCS1. Both the external and internal flash
devices are powered by the internal regulator FLASH_1V8_OUT (Pin #17).
4.3.9.
SAR_VAINPx (Pins #83, #29, #84 and #30)
The ALT1210MOD-VZ-01 has 4 ADC converters to measure external signals. The
readings can be done by AT command or from the application layer.
4.3.10.
SPI Master (Pins #107, #108, #54, #55 and #63)
This is a 4 wire bus, with two chip select lines in order to allow the module to be
able to control two separate slave devices.
4.3.11.
SPI Slave (Pins #66, #68, #69, #12 and #67)
This is the primary interface to the host. The Host is the Master on the bus.
4.3.12.
PCM (Pins #53, #52, #105, and #106)
This is an AUDIO interface to be connected to voice hub or codec devices in order
to enable voice enbled devices. Please contact Altair application team for specific
requirements and availability of such options.
4.3.13.
GPIOs
Digital IOs can be used by the application layer as general purpose IOs. Please see
section 3.3 or contact Altair Application team for more information on how to use
these pins for different purposes.
