AT91RM3400
The AT91PS_Buffer is a pointer to the AT91S_Buffer structure manages the buffers. This
structure embeds the following functions:
•
•
All the functions can be overloaded by the application to adapt buffer management.
A simple implementation of buffer management for the Xmodem Service is provided in the
boot ROM source code.
