State Machine
The parallel port is controlled by a large synchronous state machine. The state machine is based on
the IEEE STD 1284 specification and conforms to all the functional modes (except extensibility
link options, none of which are currently — as of the print date of this document — defined).
Configuration
At power-up, the interface begins in Compatibility mode (Centronics mode) ready to accept data
from the master. Only the ETxfr bit (PCR[5]) is required to allow transfers in Compatibility mode
(parallel port only; datapath section is separate). PCR[7:5] enable transfers and Negotiation and
Manual modes.
