Using SPI of Motorola Microcontrollers

[gnsassoc]

Hi everyone,

I need to interface a real-time clock, an external memory and other components to the Motorola uC - 68hc908gp32. The common way to do it is to interface these components to the uC's SPI, serial peripheral interface. :roll: errr... the problem is there's only one SPI in an uC!

Anyone any idea whether there is any better way to solve this problem?

hrmmm....mebbe u should try bus topology to control a few devices using SPI...
