21.2 Modes of Operation
The ECAN 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
(CiCTRL1<10:8>). Entry into a mode is Acknowledged
by monitoring the OPMODE<2:0> bits
(CiCTRL1<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.
