message, before accepting an incoming message.
This feature allows the CAN unit to directly support the
use of higher CAN protocols, which make use of the
first and/or second byte of data as a part of the accep-
tance layer for storing incoming messages. Program
each message center independently to perform testing
of the incoming data with or without the use of the glob-
al masks.
Global controls and status registers in the CAN unit
allow the C to evaluate error messages, validate new
data and the location of such data, establish the bus
timing for the CAN bus, establish the identification
mask bits, and verify the source of individual mes-
sages. In addition, each message center is individually
equipped with the necessary status and controls to
establish directions, interrupt generation, identification
mode (standard or extended), data field size, data sta-
tus, automatic remote frame request and acknowledg-
ment, and masked or nonmasked identification
acceptance testing.
UART Interface
Use the 8051-style universal synchronous/asynchro-
nous receiver/transmitter (UART) capable of interfacing
with a LIN transceiver for serial interfacing. Figure 11a
shows the UART block diagram in synchronous mode
and Figure 11b shows asynchronous mode. The UART
allows the device to conveniently communicate with
other RS-232 interface-enabled devices, as well as PCs
and serial modems when paired with an external RS-
232 line driver/receiver. The UART can detect framing
errors and indicate the condition through a user-acces-
sible software bit. The time base of the serial port is
derived from either a division of the system clock or the
dedicated baud clock generator. The UART is capable
of supporting LIN protocol implementation in software
when using one of the timers for autobaud detection.
Table 1 summarizes the operating characteristics as
well as the maximum baud rate of each mode. Refer to
the
MAXQ7665/MAXQ7666 User’s Guide for detailed
UART information.
