FSIZ4:0 — FIFO Size Bits
The FSIZR register can only be written if the SFTRES bit in the Module
Configuration register is set.
BIT 6
These bits are used to configure the FIFO. The number of buffers,
starting from buffer ‘0’, assigned to the receive FIFO can be selected.
The corresponding buffer(s) must be assigned as Receive buffer by
the CFG-bits in the message buffer control register(s).
