Description

Output Control Register

Fields

SDOC

SDA Output Control

0 (0): I3C drives the SDAn pin low.

1 (1): I3C releases the SDAn pin.

SCOC

SCL Output Control

0 (0): I3C drives the SCLn pin low.

1 (1): I3C releases the SCLn pin.

SOCWP

SCL/SDA Output Control Write Protect

0 (0): Bits SCOC and SDOC are protected.

1 (1): Bits SCOC and SDOC can be written (When writing simultaneously with the value of the target bit). This bit is read as 0.

EXCYC

Extra SCL Clock Cycle Output

0 (0): Does not output an extra SCL clock cycle (default).

1 (1): Outputs an extra SCL clock cycle.

SDOD

SDA Output Delay

0 (000): No output delay

1 (001): 1 I3Cφ cycle (When OUTCTL.SDODCS = 0 (I3Cφ)) 1 or 2 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

2 (010): 2 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 3 or 4 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

3 (011): 3 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 5 or 6 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

4 (100): 4 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 7 or 8 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

5 (101): 5 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 9 or 10 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

6 (110): 6 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 11 or 12 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

7 (111): 7 I3Cφ cycles (When OUTCTL.SDODCS = 0 (I3Cφ)) 13 or 14 I3Cφ cycles (When OUTCTL.SDODCS = 1 (I3Cφ/2))

SDODCS

SDA Output Delay Clock Source Selection

0 (0): The internal reference clock (I3Cφ) is selected as the clock source of the SDA output delay counter.

1 (1): The internal reference clock divided by 2 (I3Cφ/2) is selected as the clock source of the SDA output delay counter.
