7 PON 128
Power-on detection. Power has been
turned off and on since the last time the
event register was read or cleared.
3.3 Status Byte Register
The status byte register reports the status information of other status registers. Query
data waiting in the output buffer of the power supply is immediately reported
through the bit4 (MAV, Message Available Bit) of the status byte register. Bits in the
SUMMARY register of the status byte register are not latched. Clearing an event
register will clear the corresponding bits in the status byte SUMMARY register.
Reading all messages in the output buffer, including pending queries, will clear the
bit4 (MAV, Message Available Bit). The definitions of the bits in the status byte
register and the decimal values corresponding to their binary weights are as shown in
the table below.
