Parallel Interface Communication
In parallel mode, the start condition is generated on the rising edge of the I/O_7 pin while the CLK is high.
This is used to reset the interface logic. Figure 5-5 shows the sequence of the data, with an 8-bit address
word first, followed by data.
Communication is ended by:
the StopSmpl condition, where the falling edge on the I/O_7 pin is expected while CLK is high
the StopCont condition, where the I/O_7 pin must have a successive rising and falling edge while CLK
is low in order to reset the parallel interface and be ready for the new communication sequence
The StopSmpl condition is also used to terminate the direct mode.
