MXcom "C-BUS" interface to PIC question

[tcbcats]

I need to interface with a MX829 Baseband Signal Processor that Has a MX-com "C-BUS" interface. This interface is a MX-com defined standard but I am told it may be compatable with some PICBASIC I/O commands.
Has anyone interfaced a PIC with this part or to the MX-com "C-BUS"?

"C-BUS" has a serial clock, Command data, Reply Data, CS line and IRQ line.

After checking the datasheet, it sound to me like a variant of SPI/microwire. Shiftin/Shiftout or the use of the MSSP i guess.

I am also trying to use the c-bus protocol with no luck. I am working with a cmx-823ds.

If anyone has any ideas I would appreciate the help. Thanks!
