the interframe space (i.e., frame reception or transmission is in progress), and the CAN module enters the initialization
mode at the first bit in the interframe space (the values of the OPMODE2 to OPMODE0 bits are changed to 000B). After
issuing a request to change the mode to the initialization mode, read the OPMODE2 to OPMODE0 bits until their values
become 000B to confirm that the module has entered the initialization mode (see Figure 20-37).
20.8.5 Resetting error counter C0ERC of CAN module
status is made, set the C0CTRL.CCERC bit to 1 in the initialization mode. When this bit is set to 1, the C0ERC and
C0INFO registers are cleared to their default values.

The transition from the initialization mode to an operation mode is controlled by the C0CTRL.OPMODE2 to
