OPERATIONAL DESCRIPTION
MSM9225 operation is described below.
Operational Procedure
Procedures to set and operate various communication protocols are indicated below.
1. Initial setting
The initial setting procedure is indicated below.
Start initial setting
Set INIT bit of CANC register
(0Ehex) to "1"
Read INIT bit
INIT = 1?
Set the number of messages with
the NMES register (1Ehex)
Set the inside message
control register (X0hex)
Set the message unit
(FRM/DCL3-DCL0, /ID28-ID0)
All message
settings complete?
Set the interrupt control with the
CANI register (0Fhex)
Initial setting complete
Set INIT bit of the CANC register
(0Ehex) to "0".
Group message settings
(GMR/GMSK)
Set Tx0, Tx1, Rx0, Rx1 states
with the TIOC register (2Fhex)
CAN bus timing settings
BTR0 (1Fhex)
BTR1 (2Ehex)
YES
NO
*) Since the INIT bit cannot be set to "1" during
transmission or reception, read and verify its value.
