On this chip, the procedure to enter Stop mode is:
1. Enter Freeze mode by following the procedure described in
2. Request Stop mode.
3. Poll MCR until CAN_MCR[LPMACK] is set to 1. The minimum timeout duration
for setting CAN_MCR[LPMACK] is 2 CAN Nominal bits.
49.2 Introduction
The FlexCAN module is a communication controller implementing the CAN protocol
according to the ISO 11898-1 standard and CAN 2.0 B protocol specifications. A general
block diagram is shown in
, which describes the main subblocks implemented
in the FlexCAN module, including:
• One associated memory for storing message buffers
• Receive Global Mask registers
• Receive Individual Mask registers
• Receive FIFO filters
• Receive FIFO ID filters
The functions of the submodules are described in subsequent sections.
NOTE
Rx FIFO cannot be used in FD mode.
