[Bits 9 to 0] 10-bit slave address mask bits
These bits mask the bits of the 10-bit slave address register (ITBA). Write to this register when the
2
I C interface is disabled (ICCR EN = 0).
Value
0
1
Setting this bit enables transmission of an acknowledge to a compound 10-bit slave address. When using
this register for comparison of 10-bit slave addresses, set this bit to "1". The received slave address is
overwritten to ITBA. When ASS = 1 (IBSR), the specified slave address can be determined by reading
the ITBA register.
Each bit of TM9 to "0" of ITMK corresponds to one bit of the ITBA address. If the value of each of the
TM9 to 0 bits is "1", the ITBA address becomes valid; if it is "0", the ITBA address becomes invalid.
Example: ITBA address is 0010010111
The slave address is in the space from 0010010100
