Description
SDAO Write Protect
This bit 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 by the MOV instruction. This bit is always read
as 1.
This bit 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, and cannot be modified.
IIC Control Part Reset
This bit resets the control part except for I
this bit is set to 1 when hang-up occurs because of
communication failure during I
part can be reset without setting ports and initializing
registers.
Reserved
This bit is always read as 1, and cannot be modified.
