Fig.14 Emergency deactivation sequence after VCC short circuited to ground.
Auxiliary contacts C4 and C8
The auxiliary contacts C4 and C8 are controlled by ports
P34 and P35 through two identical pseudo-bidirectional
I/O lines.
In the Idle state, port P34 is pulled HIGH to VDD by an
integrated 20 k
resistor and C4 is pulled HIGH to VCC by
an integrated 10 k
resistor. This allows operation with a
VCC value of 3 V and a VDD value of 5 V. The first side on
which a falling edge occurs becomes the master.
An anti-latch circuit disables the detection of a falling edge
on the other side, which becomes the slave.
After a delay of approximately 200 ns (td), the N transistor
on the slave side is turned on which transmits the ‘0’
present on the master side. When the master side goes
back to logic 1, the P transistor on the slave side is turned
on during td, and then both sides return to their idle states.
The maximum frequency on the I/O lines is 1 MHz.
