AT-AO-6/10 Digital I/O
The AT-AO-6/10 contains eight bits of digital I/O. These bits are divided
into a set of two digital I/O ports of four bits each. The 4-bit digital I/O ports
are labeled as ports DIOA and DIOB. These ports are referred to as ports 0
and 1 by the Digital I/O functions, in which:
• Port DIOA = port 0
• Port DIOB = port 1
You can configure port 0 or 1 as either an input or an output port. Any port
that you configured as an output port has read-back capability. The
AT-AO-6/10 digital I/O ports operate in nonlatched mode only.
