register (corresponds to 6 wait states when accessing the XDATA area). 
Depending on the application, it is helpful to set the wait states only when 
accessing the CAN controller. If parts of a program is only working with data 
from the RAM, the wait states should be cancelled. 
For the Philips SJA1000, 4 wait states (010b) are sufficient. 

4.5  Serial Interfaces 

Up to two serial interfaces according to RS232C standard can be assembled on 
the card. The interfaces are operated by the microcontroller via the integrated 
serial interfaces of the DS80C320 on the port pins P3.0/P3.1 and P1.2/P1.3.
