The receive and input both use P1
and P2 buffer pointers. However,
they use them in a mutually
exclusive way. *rx_fbuff_base
switches to P2 at the same time
*in_fbuff_base switches to P1.
The output and transmit both use P3
and P4 buffer pointers. However,
they use them in a mutually
exclusive way. *out_fbuff_base
switches to P4 at the same time
*tx_fbuff_base switches to P3.
