各位好，
最近在使用SDFM的内部比较器时遇到了问题，无法正常触发over/under value 的状态。
根据iddk的代码，hlt = 0x7fff, llt = 0
将其改变为hlt = 100。并没有触发相应标志位，
代码如下：
#define SDFM_TICKS 5
#define OSR_RATE OSR_127
/*******************************************************/
/* Input Control Module */
/*******************************************************/
//Configure Input Control Mode: Modulator Clock rate = Modulator data rate
Sdfm_configureInputCtrl(1,FILTER1,MODE_0);
Sdfm_configureInputCtrl(1,FILTER2,MODE_0);
Sdfm_configureInputCtrl(1,FILTER3,MODE_0);
/*******************************************************/
/* Comparator Module */
/*******************************************************/
//Comparator HLT and LLT
//Configure Comparator module's comparator filter type and comparator's OSR value,
// high level threshold, low level threshold
Sdfm_configureComparator(1, FILTER1, SINC1, OSR_8, HLT, LLT);
Sdfm_configureComparator(1, FILTER2, SINC1, OSR_8, HLT, LLT);
Sdfm_configureComparator(1, FILTER3, SINC1, OSR_8, HLT, LLT);
/*******************************************************/
/* Sinc filter Module */
/*******************************************************/
//Configure Data filter modules filter type, OSR value and enable / disable data filter
// 16 bit data representation is chosen for OSR 128 using Sinc3, from the table in the TRM
// the max value represented for OSR 128 using sinc 3 is +/-2097152 i.e. 2^21
// to represent this in 16 bit format where the first bit is sign shift by 6 bits
Sdfm_configureData_filter(1, FILTER1, FILTER_ENABLE, SINC3, OSR_RATE, DATA_16_BIT, SHIFT_6_BITS);
Sdfm_configureData_filter(1, FILTER2, FILTER_ENABLE, SINC3, OSR_RATE, DATA_16_BIT, SHIFT_6_BITS);
Sdfm_configureData_filter(1, FILTER3, FILTER_ENABLE, SINC3, OSR_RATE, DATA_16_BIT, SHIFT_6_BITS);
//PWM11.CMPC, PWM11.CMPD, PWM12.CMPC and PWM12.CMPD signals cannot synchronize the filters. This option is not being used in this example.
Sdfm_configureExternalreset(1,FILTER_1_EXT_RESET_ENABLE, FILTER_2_EXT_RESET_ENABLE, FILTER_3_EXT_RESET_ENABLE, FILTER_4_EXT_RESET_ENABLE);
DELAY_US(1000000);
Sdfm_configureInterrupt(1, FILTER1, IEH_ENABLE, IEL_ENABLE, 0, 0);
Sdfm_configureInterrupt(1, FILTER2, IEH_ENABLE, IEL_ENABLE, 0, 0);
Sdfm_configureInterrupt(1, FILTER3, IEH_ENABLE, IEL_ENABLE, 0, 0);
// Enable master filter bit of the SDFM module 1
Sdfm_enableMFE(1);
Sdfm_enableMIE(1);
