To protect against wrong or illegal SPI instructions, the SBC detects the following SPI
failures:
Any control bit which can be set by software is readable by the application. This allows
software debugging as well as control algorithms to be implemented.
Watchdog serving and mode setting is performed within the same access cycle; this only
allows an SBC mode change whilst serving the watchdog.
Each register carries 12 data bits; the other 4 bits are used for register selection and
read/write definition.
The SPI interface gives access to all SBC registers; see
A0) of the message header define the register address, the third bit is the read register
select bit (RRS) to select one out of two possible feedback registers; the fourth bit (RO)
allows ‘read only’ access to one of the feedback registers. Which of the SBC registers can
be accessed also depends on the SBC operating mode.

SPI clock count failure (wrong number of clock cycles during one SPI access): only
16 clock periods are allowed within one SCS cycle. Any deviation from the 16 clock
cycles results in an SPI failure interrupt, if enabled. The access is ignored by the SBC.
In Start-up and Restart mode a reset is forced instead of an interrupt
Forbidden mode changes according to
Illegal Mode register code. Undefined operating mode or watchdog period coding
results in an immediate system reset; see
