3.5.3
The current Receive and Transmit Error Counters (REC and TEC) can be read, as can
the EFLG register. The is the same as the “Read CAN Error” Information Request
Message (IRM).
3.5.4
The bit timing (CNF registers) cannot be changed from the default values. However,
these registers can be read and displayed along with the parsed prescaler and T
settings.
3.5.5
This window implements the command messages as described in the data sheet. Both
IRMs and input messages can be implemented by selecting the appropriate radio
button (see Figure 3-4).
This window also gives the added functionality of reading and/or writing individual
registers. Reading individual registers is actually an IRM that contains the desired
register (e.g., reading IOINTEN register is actually a “Read Control Register” IRM
command with the resulting output message). Writing an individual register is a “Write
Register” input command.
