Transmitting Data

A7 A6 A5 A4 A3 A2 A1

D7 D6 D5 D4 D3 D2 D1 D0

SDA

SCL

SSPIF

ACKDT

ACKSTAT

CKP

R/W

D/A

Received address

is read from SSPBUF

BF is automatically

cleared after 8th falling

edge of SCL

Data to transmit is

loaded into SSPBUF

Cleared by software

Slave clears

ACKDT to ACK

address

Master’s ACK

response is copied

to SSPSTAT

CKP not cleared

after not ACK

Set by software,

releases SCL

ACKTIM is cleared

on 9th rising edge of SCL

ACKTIM is set on 8th falling

edge of SCL

When AHEN = 1;

CKP is cleared by hardware

after receiving matching

address.

When R/W = 1;

CKP is always

cleared after ACK

Master sends

Stop condition

ACK

R/W = 1

Master releases SDAx

to slave for ACK sequence

ACK

ACKTIM
