Hello,
I need to write some data into an EEPROM using the iic bus. From the MPC860
user manual I was not able to figure out the method to send the trasmit
buffer.
As per the manual, I need to mention the device address as the first byte to
be transmitted i.e. first byte in tbdf->cbd_bufadr . If so, where do I
mention
the actual buffer which contains the data that needs to be written to the
EEPROM ?
I would greatly appreciate any help.
Thanks,
Ajay

In the same buffer following the device byte, or in a following BD
when the buffer containing the device byte does not have the last (L)
indicator in the BD control/status.
