Section 15 Controller Area Network (HCAN)
15.7
A bus transceiver IC is necessary to connect this chip to a CAN bus. A Philips PCA82C250
transceiver IC is recommended. Any other product must be compatible with the PCA82C250.
Figure 15.16 shows a sample connection diagram.

15.8.1
HCAN operation can be disabled or enabled using the module stop control register. The initial
setting is for HCAN operation to be halted. Register access is enabled by clearing module stop
mode. For details, refer to section 20, Power-Down Modes.
15.8.2
The HCAN is reset by a power-on reset, in hardware standby mode, and in software standby
mode. All the registers are initialized in a reset, however mailboxes (message control
(MCx[x])/message data (MDx[x])) are not. After power-on, mailboxes (message control
(MCx[x])/message data (MDx[x])) are un-initialized, and their values are undefined. Therefore,
mailbox initialization must always be carried out after a power-on reset, a transition to hardware
standby mode, or software standby mode. The reset interrupt flag (IRR0) is always set after a
power-on reset or recovery from software standby mode. As this bit cannot be masked in the
interrupt mask register (IMR), if HCAN interrupt enabling is set in the interrupt controller without
clearing the flag, an HCAN interrupt will be initiated immediately. IRR0 should therefore be
cleared during initialization.
