19.5.19 CANn control register (CnCTRL)

The CnCTRL register is used to control the operation of the CAN module.

This register can be read/written in 16-bit units.

The C2CTRL register is valid only in models

PD703089Y and 70F3089Y.

Cautions 1. Both bitwise writing and direct writing to the CnCTRL register are prohibited. Attempts to

write directly to this register may result in operation faults, so be sure to follow the sequence

described in 19.6 Cautions Regarding Bit Set/Clear Function.

2. When writing to the CnCTRL register, set or clear bits according to the register configuration

shown in part (b) Write of the following figure.

3. When canceling CAN stop mode, CAN sleep mode must be cancelled at the same time.
