The ECANx module can operate in one of several
operation modes selected by the user. These modes
include:
• Initialization mode
• Disable mode
• Normal Operation mode
• Listen Only mode
• Listen All Messages mode
• Loopback mode
Modes are requested by setting the REQOP<2:0> bits
(CxCTRL1<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits (CxCTRL1<7:5>).
The module does not change the mode and the
OPMODE bits until a change in mode is acceptable,
generally during bus Idle time, which is defined as at least
11 consecutive recessive bits.
