status.questionable.setmap()
This function maps events to bits in the questionable event registers.
Type TSP-Link accessible
Affected by Where saved Default value
Function
Yes
Usage
status.questionable.setmap(bitNumber, setEvent)
status.questionable.setmap(bitNumber, setEvent, clearEvent)
bitNumber
The bit number that is mapped to an event (0 to 14)
setEvent
The number of the event that sets the bits in the condition and event registers; 0 if
no mapping
clearEvent
The number of the event that clears the bit in the condition register; 0 if no mapping
Details
You can map events to bits in the event registers with this command. This allows you to cause bits in
the condition and event registers to be set or cleared when the specified events occur. You can use
any valid event number as the event that sets or clears bits.
When a mapped event is programmed to set bits, the corresponding bits in both the condition register
and event register are set when the event is detected.
When a mapped event is programmed to clear bits, the bit in the condition register is set to 0 when
the event is detected.
If the event is set to zero (0), the bit is never set.
See Event numbers (on page C-10) for information about event numbers.
Example
status.questionable.setmap(0, 4916, 4917)
When event 4916 (the buffer is 0 % filled)
occurs, bit 0 is set in the condition register
and the event register of the Questionable
Event Register. When event 4917 (buffer is
100 % filled) occurs, bit 0 in the condition
register is cleared.
