Normal and ATE mode: differences
The
supports two main modes of operation:
•
Normal (or running)
: is the GUI normal operation mode (described in the previous chapter)
•
ATE
: is mainly used to program the STNRG011 NVM section and is based on the ATE protocol
Table 4.
Differences between normal and ATE modes

Metering information
Available through the metering protocol (STNRG011 to host)
Not available
ATE protocol
No (default)
Yes
Communication
STNRG011→Host only (default)
Bi-directional
PFC/LLC operations
Yes
No
STNRG011 supply
Self-supplied
External supply
NVM write
No
Yes
Note:
It is also possible to enable the ATE protocol in running mode for bidirectional communication. This requires a
specific patch to enable the UART uplink communication.
Note:
If the ATE protocol is enabled during Normal mode, the GUI is able to handle simultaneously Metering information and ATE
protocol. However, the bandwidth on the UART link might be impacted. So, it is recommended to disable the metering
protocol by checking the Disable Asynchronous STNRG011 Power messages box.
