Section 16 I
16.3.7
Setting the SW bit to 1 in DDCSWR enables formatless mode to be selected as the IIC0 operating
mode. Switching from formatless mode to the I
automatically when a falling edge is detected on the SCL pin.
The following four preconditions are necessary for this operation:
Automatic switching is performed from formatless mode to the I
DDCSWR is automatically cleared to 0 on detection of a falling edge on the SCL pin. Switching
from the I
DDCSWR to 1.
In formatless mode, bits (such as MSL and TRS) that control the I
must not be modified. When switching from the I
bit to 1 or clear it to 0 according to the transmit data (transmission or reception) in formatless
mode, then set the SW bit to 1. After automatic switching from formatless mode to the I
format (slave mode), in order to wait for slave address reception, the TRS bit is automatically
cleared to 0.
If a falling edge is detected on the SCL pin during formatless operation, the I
operating mode is switched to the I
detected.
