Writing a one to this bit will force the appearance of an arbitration loss on the next one a master attempts
to transmit.
Writing a one to this bit will force the appearance of a receive acknowledge to the byte level state machine
at bit 9 of the transfer.
Writting a one to this bit will force an output enable at the pad. The pad data line is tied to zero. Thus the
I2C data line will either be hi-z or zero.
Writing a one to this bit will force an output enable at the pad. The pad data line is tied to zero. Thus the I2C
clock line will either be hi-z or zero.
Fixed read-only value reflecting the MAJOR field of the RTL version.
Fixed read-only value reflecting the MINOR field of the RTL version.
Fixed read-only value reflecting the stepping of the RTL version.
