Datasheet
8.6.4.2
A Receive Buffer Address Register — Upper (ARBADRU)
8.6.4.3
B Receive Buffer Address Register — Lower (BRBADRL)
8.6.4.4
B Receive Buffer Address Register — Upper (BRBADRU)
These registers contain the start addresses of two external buffers that are used by the CD2231 to
store the next two receive data blocks. They are written to by the host and copied internally to
control the data transfer to the memory.
