Section 18 Controller Area Network (HCAN) [H8S/2556 Group]
18.7
A bus transceiver IC is necessary to connect this LSI to a CAN bus. A Philips PCA82C250
transceiver IC is recommended. Any other product must be compatible with the PCA82C250.
Figure 18.16 shows a sample connection diagram.
18.8
18.8.1
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, see section 22, Power-Down Modes.
18.8.2
The HCAN is reset by a power-on reset or in hardware standby mode, software standby mode,
watch mode, or module stop 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 initialized, and their values are undefined.
Therefore, mailbox initialization must always be carried out after a power-on reset or recovery
from hardware standby mode, software standby mode, watch mode, or module stop mode. The
reset interrupt flag (IRR0) is always set after a power-on reset or recovery from software standby
