The 24 I/O ports are configurable by group. There are 10 groups:
□
The groups #1 to #8 contain
2 single-ended I/O ports
.
□
The groups #9 and #10 contain
4 single-ended I/O ports
.
Within a group, it is allowed to set
all
the I/O ports:
□
for TTL input operation
OR
...
□
for 5 V CMOS output operation.
TIP
The configuration is saved into a non-volatile memory on the I/O module.
The configuration is automatically restored after applying power.
