FCAL_EN is not necessarily issued

 tx_array[2] = (unsigned char) (r[112]) & (0xFF); 

This code that should issue a FCAL_EN command is not quite right per the documentation for the LMX2594, something like:

tx_array[2] = (unsigned char) ((r[112]) & (0xFF)) | (1 << 3));

would ensure this rather than rewriting R0 with whatever value was in place
