Description
0
I2UM0EN
This bit is used to enable the master operation. When "1" is written to this bit, the I2UM0ST
bit can be set and the I2UM0BB bit starts operation. When "0" is written to this bit, the I2C
master stops operation and the I2UM0RD, I2UM0SA, I2UM0TD and I2UM0CON registers
are initialized.
In the case "0" is written to this bit during the communication, initialize the I
2
C bus unit and
reconfigure it.
0: Stop the I
2
C master operation (initial value)
1:
Enable the I
2
C master operation
[Note]
Ÿ
When using the high-speed clock for the I
2
C operation, specify the following I
2
C operating clock
frequency depending on the mode and the reference frequency of the PLL oscillation.
