Control Codes
The μPD71055 can operate in one of 3 modes.
The first (Mode 0) provides for simple inputs and outputs for three, 8 bit ports.
Data is written to or read from a specified port (A, B, or C) without the use of
handshaking.
The following table gives a summary of the most commonly used ‘Control
Words’ which must be written to the control port to configure the μPD71055
I/O ports in Mode 0.

Mode 1 enables the transfer of data to or from a specified 8 bit port (A or B) in
conjunction with strobes or handshaking signals on port C.
In Mode 2, data is transferred via one bi-directional 8 bit port (A) with
handshaking (port C).
Refer to the μPD71055 or i8255 data sheet for full details of the settings and use
of Modes 1 and 2.
