Datasheet
Channel Option Register Change Command
Changes made to some Channel Option register bits must be signalled to the CD1865 by this
command. Any combination of COR changes may be indicated by one command. All of the bits in
COR3 take effect immediately, and all of the bits in COR2 (except LLM) take effect immediately.
In other words, when changing COR3 or any of COR2 (except LLM), it is not necessary to issue a
Channel Option register Change Command. However, to preserve compatibility with older
CD1865 designs, it is acceptable to set these bits.
