SPI Modes
The Airborne device supports the following four SPI modes. These are selectable
through the command line or web interfaces. The default mode is zero (0).

Table 16 - SPI Command Description

Description
The NOP command does nothing.
It is intended to be used when the host wants to simply retrieve
the RX Message Header without any other operation.
PARM1 and PARM2 are unused for this command and should
be set to zero.
The BREAK command will issue a break sequence to the
module.
It is analogous to the BREAK signal on a common UART. Use
this command to issue a BREAK if the esc-mode-serial brk
setting is configured in the module.
PARM1 and PARM2 are unused for this command and should
be set to zero.
The TXINTCLR command will clear the TX interrupt.
Use this command when the module is issuing a TX interrupt
but the host has no more data to send. This is analogous to the
reset TX interrupt command on a common UART. The result of
this command is that the TX interrupt is cleared even though the
host is not writing more data to the module.
PARM1 and PARM2 are unused for this command and should
be set to zero.
