Programmable Registers
27.5.5 I2C Control Register 1 (HW_I2C_CTRL1)
The I2C Controller Command is further defined by fields in this control extension register.
The I2C Control Register 1 is where the I2C slave address is specified. Fast or normal mode
is selected here.
HW_I2C_CTRL1: 0x040
HW_I2C_CTRL1_SET: 0x044
HW_I2C_CTRL1_CLR: 0x048
HW_I2C_CTRL1_TOG: 0x04C
This control register is primarily used for interrupt management. It also controls the special
slave address matching mode. In addition, it controls the protocol speed, i.e fast or 400KHz
versus normal or 100KHz operation.
EXAMPLE
HW_I2C_CTRL1_CLR(BM_I2C_CTRL1_SLAVE_IRQ); // clear the slave interrupt
