Technical discussions about Freescale (Motorola) DSPs (including the DSP56000, DSP56300, DSP56600, 56800 DSPs).
Hi, I would like to configure pin 0-1 to PhaseA1/PhaseB1 and pins 2-3 to SCI (MISO and MOSI). However the manual is not clear about if this is possible (reading about the SIM_GPS). It seems that all four GPIOC pins [0:3] have to be configured to the same function (GPIO OR Quad decoder/Quad Time B OR SPI1) even though the actual configuration through SIM_GPS is done individually. My conclusion is that I will not be able to use GPIOC pin 2 and 3 sor SPI1 signals even though the Quadrature decoder is configured to operating mode 2 (ie only using filtered PHASEA and PHASEB signals). Is my conclusion correct? If not where is the information that supports this?
