Programming the Device
PRELIMINARY
6.4
Indirect Configuration Register Access
It is possible to read the current SWITI configuration with an indirect register access for
analyze and test purpose. There are five commands in the
CMD2
register which can be
used to read the configuration. The clock generator output signal and external
configuration for the SWITI can be read with the ’Read Configuration Command’. The
four instruction bits select one possible configuration command. The current
configuration is determined by the command written in the
TSV
register. The
configuration information for every command can be found on page 40.
The line configuration can be read with the command ’Read Local Bus Line
configuration’. Before the command will be issued the
SPA
or
DPA
register must be
written with the port number. The configuration for the selected line is written in the
TSV
register by the internal controller. The interrupt handling is described in
Chapter
6.2. The
bit shift configuration can be read with the command ’Read Bit Shift Configuration’ and
the dataflow is the same as described above.
With the command ’Read GPCLK Configuration’ it is possible to read the configuration
for every GPCLK line. If this command is written the configuration can be read from the
TSV
and
CON
register. The
CON
register is not interrupt controlled and will keep the last
data after a microprocessor read access.
To read the correct configuration data from the
TSV
register it is not allowed to use the
command "Read Time-Slot Value" before the
TSV
register was read.
