Description
SDA Output Value Control
This bit is used with SDAOP when modifying output
level of SDA. This bit should not be manipulated during
transfer.
0: When reading, SDA pin outputs low.
1: When reading, SDA pin outputs high.
SDAO Write Protect
Controls change of output level of the SDA pin by
modifying the SDAO bit. To change the output level,
clear SDAO and SDAOP to 0 or set SDAO to 1 and
clear SDAOP to 0. This bit is always read as 1.
SCL Output Level
Monitors SCL output level. When SCLO is 1, SCL pin
outputs high. When SCLO is 0, SCL pin outputs low.
Reserved
This bit is always read as 1. The write value should
always be 1.
IIC Control Part Reset
Resets bits BC2 to BC0 in the ICMR register and the
IIC3 internal circuits. If this bit is set to 1 when hang-up
occurs because of communication failure during I
operation, bits BC2 to BC0 in the ICMR register and the
IIC3 internal circuits can be reset by setting this bit to 1.
Reserved
This bit is always read as 1. The write value should
always be 1.
When writing, SDA pin is changed to output low.
When writing, SDA pin is changed to output Hi-Z
(outputs high by external pull-up resistance).
