7.2.1.5 I/O configuration
Table 14.
The I/O configuration is done via the LIN configuration request ‘Data Dump’, where the
first data byte of the MasterReq contains the slave node address NAD. The I/O-pin
configuration process starts only, if the received slave node address matches the own
UJA1023 node address and if data byte D2 (SID) is 0xB4.
As with the other configuration commands, the master transmits the I/O-pin configuration
data via the MasterReq message. Due to the limited amount of data bytes within the LIN
configuration command ‘Data Dump’, the configuration and diagnosis is split-up into four
blocks. The configuration and diagnosis blocks are distinguished on bits 6 and 7 of data
byte D3. The master can review the new configuration data via the SlaveResp message.
Finally if the master considers the received configuration data of the LIN-I/O to be correct,
it can enable the slave I/O-configuration by using the UJA1023 message frames (see
Section
It should be noted that for correct I/O configuration, the configuration requests must be
sent in sequential order of: first, second and third configuration data block.
