Description

CLEAR_LATCH determines whether the first latched information will be cleared

 

 

 

when the information is read. For some, this provides confidence that another interrupt

 

 

 

has not occurred. The information is cleared with the word serial FETCh:LATChed?

 

 

 

command. It is also cleared if PSEUDO is set and a register read of the first latched

 

 

 

information occurs. The information is not cleared if a hardware register read is used.

 

 

 

When the information is cleared, all following reads will return a value of 0 until a new

 

 

 

first latched event occurs.

 

 

 

Note: All letters of the command are required; there is no short form of the command.
