SPC560P50x, SPC560P44x
A password mechanism is designed to grant the legitimate user access to the non volatile
memory.
Boot Assist Module (BAM)
The BAM is a block of read-only one-time programmed memory and is identical for all
SPC560Px devices that are based on the e200z0h core. The BAM program is executed
every time the device is powered-on if the alternate boot mode has been selected by the
user.
The BAM provides the following features:
●
Serial bootloading via FlexCAN or LINFlex or FlexRay.
●
BAM can accept a password via the used serial communication channel to grant the
legitimate user access to the non volatile memory.

Miscellaneous Control Module (MCM)
The MCM on this device features the following:
●
Platform configuration & revision
●
ECC error reporting for flash memory and SRAM
●
ECC error injection for RAM
3.3.18
CAN (FlexCAN)
The SPC560Px MCU contains one controller area network (FlexCAN) module. This module
is a communication controller implementing the CAN protocol according to Bosch
Specification version 2.0B. The CAN protocol was designed to be used primarily as a
vehicle serial data bus, meeting the specific requirements of this field: real-time processing,
reliable operation in the EMI environment of a vehicle, cost-effectiveness and required
bandwidth. FlexCAN module contains 32 message buffers.
The FlexCAN module provides the following features:
●
Full implementation of the CAN protocol specification, Version 2.0B
–
Standard data and remote frames
–
Extended data and remote frames
–
Zero to eight bytes data length
–
Programmable bit rate up to 1Mbit/s
●
32 message buffers of zero to eight bytes data length
●
Each message buffer configurable as Rx or Tx, all supporting standard and extended
messages
●
Programmable loop-back mode supporting self-test operation
●
Three programmable mask registers
●
Programmable transmit-first scheme: lowest ID or lowest buffer number
●
Time stamp based on 16-bit free-running timer
●
Global network time, synchronized by a specific message
●
Maskable interrupts
●
Independent of the transmission medium (an external transceiver is assumed)
●
High immunity to EMI
●
Short latency time due to an arbitration scheme for high-priority messages
