ADDRMASK - TWI Slave Address Mask Register
Accessing the DATA register will clear the slave interrupt flags and the CLKHOLD flag.
• Bit 7:1 - ADDRMASK[7:1]: Read/Write Direction
These bits in the ADDRMASK register can act as a second address match register, or an
address mask register depending on the ADDREN setting.
If ADDREN is set to zero, ADDRMASK can be loaded with a 7-bit Slave Address mask. Each bit
in ADDRMASK can mask (disable) the corresponding address bit in the ADDR register. If the
mask bit is one the address match between the incoming address bit and the corresponding bit
in ADDR is ignored, i.e. masked bits will always match.
If ADDREN is set to one, ADDRMASK can be loaded with a second slave address in addition to
the ADDR register. In this mode, the slave will match on 2 unique addresses, one in ADDR and
the other in ADDRMASK.
• Bit 0- ADDREN: Address Enable
By default this bit is zero and the ADDRMASK bits acts as an address mask to the ADDR regis-
ter. If this bit is set to one, the slave address match logic responds to the 2 unique addresses in
ADDR and ADDRMASK.
