Blackfin BF707 pin multiplexing

Hello,

I am using the ADSP_BF707 EZ_Board to develop my DSP based application.

I would like to use the SPORT0 with signals selected on PORTA (PA_12, PA_13, PA_14,) and PORTB (PB_04, PB_05,PB_06).

 

Why am I not able to set such pin configuration in CCES ? The pin multiplexing in CCES does not allow to use PortA and PortB for SPORT0 configuration. Only PortC can be used.

 

What is the meaning of a term "Multiplexed Function input tap" ? This can be seen in the Hardware refference when describing (for example) SPT0 ACLK on pin 13 of port A.  The "Multiplexed Function input tap" phrase can not be found anywhere.
