EVENT :
"1": a trigger event was detected
"0": no trigger event detected
The EVENT bit is initially cleared. If the IC receives a triggering telegram on KNX bus it ac-
knowledges this telegram by sending a BUSY acknowledge on KNX bus and sets the EVENT
bit. Any further incoming triggering telegram will not be BUSY acknowledged by the IC as
long as the host does not clear the EVENT bit by writing a "0".
Acknowledge generation based on auto address mode is not affected by the EVENT bit
state.
EN_OUT :
"1": enable output stage (pull down disabled)
"0": disable output stage (output tri-state, pull down enabled)
MASK_BUF :
"1": the trigger mask buffer was written completely
"0": the trigger buffer was not written completely yet
BUF :
"1": the trigger buffer was written completely
"0": the trigger buffer was not written completely yet
Bits MASK_BUF and BUF are set by the E981.03 after successful upload using host UART
interface. They may be written by the host directly.
1) Access via UART service and SPI possible. In case of hard or soft reset the register is reset to the hard reset value or soft reset
value respectively.

Description
alarm status register
25 byte alarm telegram buffer
length of alarm telegram (high byte)
length of alarm telegram (low byte)
The alarm state register is used to signal the state of the alarm functionality and to control sending of the alarm
telegram. Reading the register is allowed any time using any interface. Writing to the register is only recommended
to clear the SENT bit and allow resending of the alarm telegram. A successful alarm telegram transmission is con-
firmed to the host by sending a L_Data.confirm service on host UART interface.
