25.4.9 ACKNOWLEDGE SEQUENCE
The 9th SCL pulse for any transferred byte in I
dedicated as an Acknowledge. It allows receiving
devices to respond back to the transmitter by pulling
the SDA line low. The transmitter must release control
of the line during this time to shift in the response. The
Acknowledge (ACK) is an active-low signal, pulling the
SDA line low indicated to the transmitter that the
device has received the transmitted data and is ready
to receive more.
The result of an ACK is placed in the ACKSTAT bit of
the SSP1CON2 register.
Slave software, when the AHEN and DHEN bits are
set, allow the user to set the ACK value sent back to
the transmitter. The ACKDT bit of the SSP1CON2 reg-
ister is set/cleared to determine the response.
Slave hardware will generate an ACK response if the
AHEN and DHEN bits of the SSP1CON3 register are
clear.
There are certain conditions where an ACK will not be
sent by the slave. If the BF bit of the SSP1STAT regis-
ter or the SSPOV bit of the SSP1CON1 register are
set when a byte is received.
When the module is addressed, after the 8th falling
edge of SCL on the bus, the ACKTIM bit of the
SSP1CON3 register is set. The ACKTIM bit indicates
the acknowledge time of the active bus. The ACKTIM
Status bit is only active when the AHEN bit or DHEN
bit is enabled.

Preliminary
25.5
The MSSP1 Slave mode operates in one of four
modes selected in the SSP1M bits of SSP1CON1 reg-
ister. The modes can be divided into 7-bit and 10-bit
Addressing mode. 10-bit Addressing modes operate
the same as 7-bit with some additional overhead for
handling the larger addresses.
Modes with Start and Stop bit interrupts operated the
same as the other modes with SSP1IF additionally
getting set upon detection of a Start, Restart, or Stop
condition.
25.5.1 SLAVE MODE ADDRESSES
The SSP1ADD register
Slave mode address. The first byte received after a
Start or Restart condition is compared against the
value stored in this register. If the byte matches, the
value is loaded into the SSP1BUF register and an
interrupt is generated. If the value does not match, the
module goes idle and no indication is given to the soft-
ware that anything happened.
The SSP Mask register
address matching process.
“SSP1 Mask Register”
25.5.1.1 I
In 7-bit Addressing mode, the LSb of the received data
byte is ignored when determining if there is an address
match.
25.5.1.2 I
In 10-bit Addressing mode, the first received byte is
compared to the binary value of ‘1 1 1 1 0 A9 A8
0’. A9 and A8 are the two MSb of the 10-bit address
and stored in bits 2 and 1 of the SSP1ADD register.
After the acknowledge of the high byte the UA bit is set
and SCL is held low until the user updates SSP1ADD
with the low address. The low address byte is clocked
in and all 8 bits are compared to the low address value
in SSP1ADD. Even if there is not an address match;
SSP1IF and UA are set, and SCL is held low until
SSP1ADD is updated to receive a high byte again.
When SSP1ADD is updated the UA bit is cleared. This
ensures the module is ready to receive the high
address byte on the next communication.
A high and low address match as a write request is
required at the start of all 10-bit addressing communi-
cation. A transmission can be initiated by issuing a
Restart once the slave is addressed, and clocking in
the high address with the R/W bit set. The slave hard-
ware will then acknowledge the read request and pre-
pare to clock out data. This is only valid for a slave
after it has received a complete high and low address
byte match.
