MSP430 Reference Code
4.2.1
Overview
There is a MSP40 reference code offered under the TPS2388 product folder on
for basic
applications. Customers can download the code for free and develop their own system software starting
from here.
The system software supports the following features:
•
Fully compliant to IEEE802.3at PoE specification
•
Virtual Auto-Mode operation
•
Device detection and classification
•
DC disconnect
•
Faults reporting
4.2.2
Semi-Auto Mode Reference code
The reference code can support PSE systems with up to 48 ports. It keeps track of all system level
parameters as well as port level parameters for each TPS2388 device within the system.
The main actions are interrupts triggered. As long as the MSP430 receives an interrupt signal from
TPS2388 devices, it checks the interrupt status and proceeds with related actions.
The system software also keeps track of system and devices error conditions that occur, as well as any
events that affect the port states. The MSP430 communicates with the PC through UART, reporting
parameters and status of the port.
