FIGURE 27-8:

I2C SLAVE, 7-BIT ADDRESS, RECEPTION (SEN = 0, AHEN = 1, DHEN = 1)

Receiving Address

Receiving Data

Received Data

A7 A6 A5 A4 A3 A2 A1

D7 D6 D5 D4 D3 D2 D1 D0

SDA

SCL

CKP

Master sends

Stop condition

Data is read from SSPBUF

Cleared by software

SSPIF is set on

9th falling edge of

SCL, after ACK

CKP set by software,

SCL is released

Slave software

ACKTIM cleared by

hardware in 9th

rising edge of SCL

sets ACKDT to

not ACK

When DHEN=1:

CKP is cleared by

hardware on 8th falling

edge of SCL

Slave software

clears ACKDT to

ACK the received

byte

ACKTIM set by hardware

on 8th falling edge of SCL

When AHEN=1:

CKP is cleared by hardware

and SCL is stretched

Address is

read from

SSBUF

ACKTIM set by hardware

on 8th falling edge of SCL

ACK

Master Releases SDAx

to slave for ACK sequence

No interrupt

after not ACK

from Slave

ACK=1

ACK

ACKDT

ACKTIM

SSPIF

If AHEN = 1:

SSPIF is set
