C MODE)
R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0 R/W-0
ADD7 ADD6 ADD5 ADD4 ADD3 ADD2 ADD1 ADD0
bit 7 bit 0
Legend:
R = Readable bit W = Writable bit U = Unimplemented bit, read as ‘0’
-n = Value at POR ‘1’ = Bit is set ‘0’ = Bit is cleared x = Bit is unknown
Master mode
:
bit 7-0 ADD<7:0>: Baud Rate Clock Divider bits
SCL pin clock period = ((ADD<7:0> + 1) *4)/F
OSC
10-Bit Slave mode — Most Significant Address Byte:
bit 7-3 Not used: Unused for Most Significant Address Byte. Bit state of this register is a “don’t care.” Bit pat-
tern sent by master is fixed by I

C specification and must be equal to ‘11110’. However, those bits are
compared by hardware and are not affected by the value in this register.
bit 2-1 ADD<9:8>: Two Most Significant bits of 10-bit address
bit 0 Not used: Unused in this mode. Bit state is a “don’t care.”
10-Bit Slave mode
— Least Significant Address Byte:
bit 7-0 ADD<7:0>: Eight Least Significant bits of 10-bit address
7-Bit Slave mode
:
bit 7-1 ADD<6:0>: 7-bit address
bit 0 Not used: Unused in this mode. Bit state is a “don’t care.”
