Device Overview
2.3.2
Three 16-bit read-only registers provide information about the device and the MFR4300 FlexRay module
(see
The PIDR (see
decimal (in this case, ‘4300’)
The AVNR (see
number in binary coded decimal (in this case, ‘0000’).
The MVR (see
number in binary coded decimal (in this case, ‘3535’). Bits 15 to 8 of the MVR comprise the controller
host interface (CHI) version number; bits 7 to 0 comprise the protocol engine (PE) version number.
These read-only values provide a unique ID for each revision of the device.

2.4.1
The MFR4300 is available in a 64-pin low profile quad flat package (LQFP). Most pins perform two
functions, as described in
assignments.
