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.
pointers to functions that manage the read buffer
pointers to functions that manage the write buffer
