Hi,
 
QE128 64 pin has many pins for SPI1 module.
 
for SPI1
PTE0/TPM2CLK/SPSCK1 (pin 60)
PTE1/MOSI1 (pin 59)
PTE2/MISO1 (pin 54)
PTE3/SS1 (pin 53)
and
PTB2/KBI1P6/SPSCK1/ADP6 (pin 32)
PTB3/KBI1P7/MOSI1/ADP7 (pin 31)
PTB4/TPM2CH1/MISO1 (pin 19)
PTB5/TPM1CH1/SS1 (pin 18)
---------------------------------
for SPI2
PTD0/KBI2P0/SPSCK2 (pin 2)
PTD1/KBI2P1/MOSI2 (pin 1)
PTD2/KBI2P2/MISO2 (pin 46)
PTD3/KBI2P3/SS2 (pin 45)
 
 
I wonder mean of shared pins.
When I enable SPI1 module, which pin will have SPSCK1, PTE0, PTB2 or both?
If both, I will be lost 4 I/O functionality? This is bad.
 
Regards,
BP.
