22.6.3.7.2
Receive FIFO Control Data
The application can access the FIFOs at any time using the control bits in the following registers:
•
Global Interrupt Flag and Enable Register (GIFER)
•
Receive FIFO Fill Level and POP Count Register (RFFLPCR)
22.6.3.7.3
Receive FIFO Status Data
The current status of the receive fifo is provided in the following register:
•
Global Interrupt Flag and Enable Register (GIFER)
•
Receive FIFO A Read Index Register (RFARIR)
•
Receive FIFO B Read Index Register (RFBRIR)
•
Receive FIFO Fill Level and POP Count Register (RFFLPCR)
22.6.4
FlexRay Memory Layout
The controller supports a wide range of possible layouts for the flexray memory. Two basic layout modes
can be selected by the FIFO address mode bit MCR[FAM].
22.6.4.1
FlexRay Memory Layout (MCR[FAM] = 0)
shows an example layout for the FIFO address mode MCR[FAM]=0. In this mode, the
following set of rules applies to the layout of the flexray memory:
•
The flexray memory is one contiguous region.
•
The flexray memory size is maximum 64 Kbytes.
•
The flexray memory starts at a 16 byte boundary
The flexray memory contains three areas: the
message buffer header area
, the
message buffer data area
,
and the
sync frame table area
.
