19.4.3.2
Masking an address bit causes that bit to become a
“don't care”. When one address bit is masked, two
addresses will be Acknowledged and cause an
interrupt. It is possible to mask more than one address
bit at a time, which greatly expands the number of
addresses Acknowledged.
The I
masking is used or not. However, when address
masking is used, the I
multiple addresses and cause interrupts. When this
occurs, it is necessary to determine which address
caused the interrupt by checking SSPxBUF.
The PIC18F87J10 family of devices is capable of using
two different Address Masking modes in I
operation: 5-Bit Address Masking and 7-Bit Address
Masking. The Masking mode is selected at device
configuration using the MSSPMSK Configuration bit.
The default device configuration is 7-bit Address
Masking.
Both Masking modes, in turn, support address masking
of 7-bit and 10-bit addresses. The combination of
Masking modes and addresses provide different
ranges of Acknowledgable addresses for each
combination.
While both Masking modes function in roughly the
same manner, the way they use address masks are
different.
19.4.3.3
As the name implies, 5-Bit Address Masking mode
uses an address mask of up to 5 bits to create a range
of addresses to be Acknowledged, using bits 5 through

1 of the incoming address. This allows the module to
Acknowledge up to 31 addresses when using 7-bit
addressing, or 63 addresses with 10-bit addressing
(see Example 19-2). This Masking mode is selected
when the MSSPMSK Configuration bit is programmed
(‘0’).
The address mask in this mode is stored is stored in the

For any ADMSK bits that are set (ADMSK<n> = 1), the
corresponding

address Acknowledge, it is sufficient to match only on
addresses that do not have an active address mask.
In 10-Bit Address Masking mode, bits ADMSK<5:2>
mask the corresponding address bits in the SSPxADD
register. In addition, ADMSK1 simultaneously masks
the two LSbs of the address (SSPxADD<1:0>). For any
ADMSK bits that are active (ADMSK<n> = 1), the cor-
responding address bit is ignored (SPxADD<n> = x).
Also note that although in 10-Bit Address Masking
mode, the upper address bits reuse part of the
SSPxADD register bits. The address mask bits do not
interact with those bits; they only affect the lower
address bits.
