Device: AT91SAM7s512

SPI Hardware Interface, Pin connection Error in SPI properties.
No SPI Hardware Interface available, the same problem like the Hardware I2C Interface.

Macro: "COM3_SPI_TXD_Test"
When Initialise Software SPI_Master_1. CPU Pin MISO is rising to 1 Signal, all other Pins have 0 Signal. MISO Pin must also set to 0 Signal. Otherwise the Signal level is not correct at every 1. bit when SPI Start sending.

When sending in Macro Section "TX bytes 1" --> CPU MOSI Pin stay at 1 Signal
When sending in Macro Section "TX bytes 2" --> CPU MOSI Pin falling to 0 Signal and stay there

No Communication over Hardware or Software Interface possible.
