C.3 CENTRONICS
With this package, SCC2 is turned into an interface that can receive Centronics data. This
package, for example, could be used in a laser printer design requiring a Centronics inter-
face option. The package uses SCC2 (its pins and registers) in addition to PA12, PA13 or
PA11, PA14, and PA15.
The main features are as follows:
C.4 PROFIBUS CONTROLLER
Process field bus (PROFIBUS) is a UART-based master-slave protocol that specifies data
rates starting at 9.6 kbps. The PROFIBUS microcode running on the IMP RISC controller
assists the M68000 core in handling some of the time-critical PROFIBUS link layer func-
tions, leaving more of the M68000 core available for the application software.
The main PROFIBUS controller features are as follows:
C.5 AUTOBAUD SUPPORT PACKAGE
The package allows a UART to automatically detect the baud rate of a serial stream and ad-
just to it. This is useful in modem applications that must support an autobaud capability. It is
