dsPIC33EPXXX(GP/MC/MU)806/810/814 and PIC24EPXXX(GP/GU)810/814
bit 6 STREN: SCLx Clock Stretch Enable bit (when operating as I
2
C slave)
Used in conjunction with SCLREL bit.
1 = Enable software or receive clock stretching
0 = Disable software or receive clock stretching
bit 5 ACKDT: Acknowledge Data bit (when operating as I
2
C master, applicable during master receive)
Value that is transmitted when the software initiates an Acknowledge sequence.
1 = Send NACK during Acknowledge
0 = Send ACK during Acknowledge
bit 4 ACKEN: Acknowledge Sequence Enable bit
(when operating as I
2
C master, applicable during master receive)
1 = Initiate Acknowledge sequence on SDAx and SCLx pins and transmit ACKDT data bit.
Hardware clear at end of master Acknowledge sequence.
0 = Acknowledge sequence not in progress
bit 3 RCEN: Receive Enable bit (when operating as I
2
C master)
1 = Enables Receive mode for I
2
C. Hardware clear at end of eighth bit of master receive data byte.
0 = Receive sequence not in progress
bit 2 PEN: Stop Condition Enable bit (when operating as I
2
C master)
1 = Initiate Stop condition on SDAx and SCLx pins. Hardware clear at end of master Stop sequence.
0 = Stop condition not in progress
bit 1 RSEN: Repeated Start Condition Enable bit (when operating as I
2
C master)
1 = Initiate Repeated Start condition on SDAx and SCLx pins. Hardware clear at end of
master Repeated Start sequence.
0 = Repeated Start condition not in progress
bit 0 SEN: Start Condition Enable bit (when operating as I
2
C master)
1 = Initiate Start condition on SDAx and SCLx pins. Hardware clear at end of master Start sequence.
0 = Start condition not in progress
REGISTER 19-1: I2CxCON: I2Cx CONTROL REGISTER (CONTINUED)
Note 1: When performing Master operations, ensure that the IPMIEN bit is ‘0’.
