Enable Interrupt
1 = Enable I2C interrupt

I2C Controller Enable Bit
1 = Enable
0 = Disable
Set to enable I2C serial function block. When ENSI=1 the I2C serial
function enables. The multi-function pin function of SDA and SCL must set
to I2C function first.
I2C START Control Bit
Setting STA to logic 1 to enter master mode, the I2C hardware sends a
START or repeat START condition to bus when the bus is free.
