The other five Accept bits in RxCTL are used for  
destination address filtering (see Section 5.3 on  
page 87). The Accept mechanism is explained in  
more detail in Section 5.2 on page 79.

operations. It is possible to set either, neither, or  
both bits. The four corresponding pairs of bits are:  
IE Bit in RxCFG

If one of the above Interrupt Enable bits is set and  
the corresponding Accept bit is clear, the CS8900A  
generates an interrupt when the associated receive
