IIC_CR.SW_MODE_EN. At that point, the SCL and SDA
pins can be controlled by the IIC_CR SDA_OUT and
SCL_OUT bits. Writing a ‘1’ to either bit causes the cor-
responding pin to become active, i.e. be pulled low. The
SDA and SCL lines are open-collector outputs, and can
hence also be pulled low by external devices. The actual
pin state can be observed by software by examining
IIC_SR SDA_STAT and SCL_STAT bits. A 1 in these
MMIO bits indicates that the corresponding pin is cur-
rently pulled low.

The number of bytes transferred between the START
and STOP conditions from transmitter to receiver is not
limited. Each 8-bit data byte is followed by one acknowl-
edge bit. The transmitter releases the SDA line which will
pull-up to a HIGH level during the acknowledge bit time.
The receiver acknowledges by pulling the data line LOW
during this acknowledge period. The master must always
generate the SCL transitions for the acknowledge bit
time.
