Elprotronic MSP430 - F_Adj_Dco_Frequency; F_Test_Dco_Frequency

F_Adj_DCO_Frequency
F_Adj_DCO_Frequency - Adjust DCO to desired frequency and return register
value for that frequency.
VALID FPA index - ( 1 to 64 ) or 0 (ALL FPAs) executed sequentially.
Syntax:
MSPPRG_API INT_X F_Adj_DCO_Frequency( INT_X freq_Hz );
freq_Hz - 100000 to 16000000 (100kHz to 16 MHz)
Return value:
-1 - FALSE;
>=0 - DCO Register value
The DCO register value has the same format as the DCO constants saved in the Info-A segments. See
TI’s documentation for detail.
Example:
data = F_Adj_DCO_Frequency( 2000000 );
When more then one FPA is used then instruction can be executed simultaneously and register value
read after the function if finished in all targets.
F_Set_FPA_index( ALL_ACTIVE_FPA ); // select all FPA’s
F_Adj_DCO_Frequency( 2000000 );
for (n=1; n<=MAX_FPA_INDEX; n++ )
data[n] = F_LastStatus( n);
F_Test_DCO_Frequency
F_Test_DCO_Frequency - Measure DCO frequency for desired DCO register value
VALID FPA index - ( 1 to 64 ) or 0 (ALL FPAs) executed sequentially.
Syntax:
MSPPRG_API INT_X F_Test_DCO_Frequency( INT_X DCO_Const );
DCO_const - 0x0000 to 0xFFFF
Return value:
-1 - FALSE;
>=0 - DCO Frequency in Hz
Example:
