Notes

  1. AUTOFD#, INIT#, and SEL_IN# are not supported when 

the MPC8xx port is used. They are supported when the 
Peripheral I/O controller port is used.

2. BUSY, PERROR, and SEL_OUT are pulled down with 

4.7K

 resistors. All other control signals are pulled up with 

4.7K

 resistors.

Serial Port Header J18

A 10-pin header (J18 on MBX series boards) provides access to the EIA-
232 serial I/O interface. The pinouts are arranged to permit a direct ribbon 
cable connection to a DB9 male connector. The pin assignments are listed 
in the following table.

Note

For SMC1, only TXD and RXD are supported.
