Notes:
GND: Signal ground, corresponding to FMI interface display GPIO[1];
DO[16:1] is defined to be output. After the PC is powered up, the initial output
is high, DO output driving capability ≥ 20mA, high level 3.5
～
5.5V; low
level 0V
～
0.8V. On the EVOC FMI interface, the DO[16:1] serial numbers of
the configuration correspond to GPIO[17:2] serial numbers displayed on the
FMI interface;
DI[8:1] is defined as input, with 3.5V
～
5.5V high level and 0V
～
0.8V low
level; input current ≤ 25mA. In the EVOC FMI interface, the DI[8:1] numbers
of that configuration correspond to the GPIO[25:18] numbers displayed in the
FMI interface on a one-to-one basis.
