How to interface both SPI and I2C at the same time with PIC

[engr.waqas]

I want to attach two devices with PIC18F452 microcontroller,one device runs on SPI while other on I2C.
How can attach both of them since PIC18F452 has only one MSSP module.
if i use multiplexer then they do not conduct in both directions.
what to do?

use software to emulate i2c routines on two other pins and keep the spi on the mssp module. quite easy to do, you can find source code on the net.
