27.5.1 I2C Control Register 0 (HW_I2C_CTRL0)
The I2C Control Register specifies the reset state and the command and transfer size
information for the I2C controller.
HW_I2C_CTRL0: 0x000
HW_I2C_CTRL0_SET: 0x004
HW_I2C_CTRL0_CLR: 0x008
HW_I2C_CTRL0_TOG: 0x00C
This register is either written by the DMA or the CPU depending on the state of an I2C
transaction.
EXAMPLE
// turn off soft reset and clock gating
