A copy of the pad input signal for the I2C clock pad.
A copy of the pad input signal for the I2C data pad.
Always set this bit field to zero.
A read-only view of the byte enables for HW_I2C_DATA register writes. These bits are used in the I2C DMA
state machine to track the number of bytes written by the DMA. Individual bits are cleared as they are
consummed.
A read-only view on current state of clock generation state machine.
Always set this bit field to zero.
When in local slave test mode, this bit field defines the type of address generated for the slave.
0x0
0x1
0x2
0x3
Writting a one to this bit places the slave in local test mode. one of three slave address can be sent in either
read or write mode.
Always set this bit field to zero.
Writing a one to this bit will force the clock generator to send a continuous stream of clocks on the I2C bus.

RSVD4
BCAST — Broadcast, i.e. i2c address 0x00.
MY_WRITE — Send to my slave address with a RW bit equal 0.
MY_READ — Send to my slave address with a RW bit equal 1.
NOT_ME — Send to an address that is not mine, i.e. bit four is complemented.
