Table 2.14: Counter Gate Source Control Bit

CTR0GateSet

0

Gate source from “CTR0Gate” control bit (Default)

 

 

 

 

1

Gate source from digital input 0 (DI0) channel

 

 

 

CTR1GateSet

0

Gate source from “CTR1Gate” control bit (Default)

1Gate source from digital input 2 (DI2) channel

2.7.8Counter Output Destination

You can choose the output destination of counter 0 and counter 1 by setting “Output Destination control bits”- CTR0OutSet and CTR1OutSet.

Table 2.15: Counter Output Destination Control Bit

CTR0OutSet 0 Output destination to “CTR0Out” status bit (Default)

1Output destination to “CTR0Out” status bit and digital output 2 (DO2) channel

CTR1OutSet 0 Output destination to “CTR1Out” status bit. (Default)

1Output destination to “CTR1Out” status bit and digital output 3 (DO3) channel

2.7.9Counter Interrupt Flag

The interrupt flag bit is a flag indicating the status of an interrupt. It is a readable/writable bit. To find the status of the interrupt, you have to read the bit value; to clear the interrupt, you have to write “1” to this bit. This bit must first be cleared to service the next coming interrupt. Besides, you can choose if counter 0 or counter 1 generate interrupt signal by configuring “CTR0IntSet” and “CTR1IntSet” control bit.
