DMA receive buffer size in AHB system memory. The value defined by these bits determines the size of buffer to use in 
main AHB system memory when writing received data.

The value is defined in multiples of 64 bytes, thus a value of 0x01 corresponds to buffers of 64 bytes, 0x02 corresponds to 
128 bytes etc.

For example:

– 0x02:  128 bytes

– 0x18: 1536 bytes (1 

×

 max length frame/buffer)

– 0xA0: 10240 bytes (1 

×

 10K jumbo frame/buffer)

Note that this value should never be written as zero.
