Chapter 7 High-speed Counter Module AH02HC/AH04HC Bit 0 in CR19/CR47/CR75/CR103 ON * 1 OFF Comparison value 1200 ON Bit 0 in CR0/CR28/CR56/CR84 OFF 1 * Number of sampled pulses 1100+203>1200 203 Number of accumulated pulses 1303 ON * 2 Bit 3 in CR19/CR47/CR75/CR103 OFF Bit 3 in CR0/CR28/CR56/CR84 OFF ON * 3 *1: If bit 0 in CR0/CR28/CR56/CR84 is turned ON, bit 0 in CR19/CR47/CR75/CR103 will be turned ON, and the system will start the count. *2: If the number of accumulated pulses is larger than or equal to the comparison value, bit 3 in CR19/CR47/CR75/CR103 will be turned ON. If bit 3 in CR0/CR28/CR56/CR84 is turned ON, bit 3 in CR19/CR47/CR75/CR103 will be turned OFF. *3:
If bit 3 in CR0/CR28/CR56/CR84 is turned ON, bit 3 in CR19/CR47/CR75/CR103 will be reset to OFF. If bit 3 in CR19/CR47/CR75/CR103 is turned OFF, bit 3 in CR0/CR28/CR56/CR84 will be turned OFF automatically.
