// Generate an interrupt
The LUMENOLOGY r Company
The following example pseudo code illustrates the configuration of an SMB-Alert style interrupt when the light
intensity changes 20% from the current value, and persists for 2.5 seconds:
In order to generate an interrupt on demand during system test or debug, a test mode (INTR = 11) can be used.
The following example illustrates how to generate an interrupt on demand:
//Assume Interrupt Source as Channel 1
//Read current light level
Address = 0x39
Command = 0xB0
ReadWord (Address, Command, DataLow, DataHigh)
Channel1 = (256 * DataHigh) + DataLow
//Calculate upper and lower thresholds
T_Upper = Channel1 + (0.2 * Channel1)
T_Lower = Channel1 − (0.2 * Channel1)
//Write the lower threshold register
Command = 0xA8
WriteWord (Address, Command, T_Lower.LoByte, T_Lower.HiByte)
//Write the upper threshold register
Command = 0xAA
WriteWord (Address, Command, T_Upper.LoByte, T_Upper.HiByte)
//Enable interrupt
Command = 0x82
Data = 0x24
WriteByte(Address, Command, Data)
Address = 0x39
Command = 0x82
Data = 0x30
WriteByte(Address, Command, Data)
//Interrupt line should now be low
