SBUF register
It is used as the buffer register in transmission and reception.
SADDR register & SADEN register
SADDR register is combined with SADEN register to form Given/Broadcast Address for
automatic address recognition. In fact, SADEN functions as the “mask” register for SADDR
register. The following is the example for it.
The Broadcast-Address for each slave is created by taking the logical OR of SADDR and
SADEN. Zero in this result is considered as “don’t care”. Upon reset, SADDR and SADEN are
loaded with all 0s. This produces a Given-Address of all “don’t care” and a Broadcast Address of
all “don’t care”. This disables the automatic address detection feature.
