ADD<7:0>: Baud Rate Clock Divider bits
SCL pin clock period = ((ADD<7:0> + 1) *4)/F
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
compared by hardware and are not affected by the value in this register.
ADD<2:1>: Two Most Significant bits of 10-bit address
Not used: Unused in this mode. Bit state is a “don’t care”.
ADD<7:0>: Eight Least Significant bits of 10-bit address
ADD<7:1>: 7-bit address
Not used: Unused in this mode. Bit state is a “don’t care”.
MSK<7:1>: Mask bits
1 = The received address bit n is compared to SSP1ADD<n> to detect I
0 = The received address bit n is not used to detect I
MSK<0>: Mask bit for I

1 = The received address bit 0 is compared to SSP1ADD<0> to detect I
0 = The received address bit 0 is not used to detect I
