innovators for industry
Ctrl Command set_max_counts
Function Defines the maximum number of External Starts.
Call set_max_counts( Counts )
Parameters Counts Maximum number of External Starts.
As an unsigned 32-bit value.
Allowed value range: [0…(2
32
–1)].
Comments • When the specified number of External Starts has been reached, the external start
input is disabled (see set_control_mode, Bit #0 = 0).
• If Counts = 0, the number of External Starts is unlimited.
• When the RTC6 is initialized (by load_program_file), Counts is set to 0.
• The current number of External Starts can be read from the corresponding internal
counter by get_counts. The counter can be reset by set_control_mode.
RTC4RTC6 Unchanged functionality. In addition: increased value range.
RTC5RTC6 Unchanged functionality.
Version info Available as of DLL 600, OUT 600, RBF 600.

Ctrl Command set_mcbsp_freq
Function Sets the transmission frequency of the McBSP interface.
Call mcbsp_freq = set_mcbsp_freq( Freq )
Parameters Freq Desired transmission frequency of the McBSP interface in Hz.
As an unsigned 32-bit value.
Allowed value range: [4000000…16000000] (4…16 MHz).
Out-of-range values are clipped to the boundary values.
Out-of-range values cause the get_last_error return code RTC6_PARAM_ERROR to
be generated.
Result The actually set frequency in Hz.
As an unsigned 32-bit value.
With overflowing values 0 is returned.
Comments • The default transmission frequency (after initialization) is 8 MHz ( Freq = 8,000,000).
• Because not every arbitrary frequency can be implemented, set_mcbsp_freq returns
the actually set frequency.
Example: mcbsp_freq = set_mcbsp_freq(7,000,000); returns mcbsp_freq = 7,200,000 .
• The new transmission frequency only becomes effective when you re-initialize the
McBSP interface by mcbsp_init.
• The signals and operating conditions of the McBSP interface are presented in the
Chapter 4.6.6 ”McBSP/ANALOG Socket Connector”, page 84.
• Note: The receiving frequency is exclusively determined by the incoming clock pulses
and has a maximum limit of 16 MHz.
RTC4RTC6 New command.
RTC5RTC6 Unchanged functionality.
Version info Available as of DLL 600, OUT 600, RBF 600.
