User or Standard Boot Selection
The first half of the Flash memory is accessible at its base address.
The second half of the Flash memory is accessible at its base address. This
authorizes users to download their own application software in this part and to
boot on it.
Push Button Enabling
SW1-4 inputs to the AT91 are valid.
SW1-4 inputs to the AT91 are not valid. This authorizes users to connect the
corresponding PIO to their own resources via the I/O expansion connector.
R(eturn) TCK ICE Signal Synchronization
The TCK signal from the JTAG interface can be synchronized with MCKO
signal and returns to the JTAG interface. (RTCK)
The TCK and RTCK ICE signals are not synchronized with MCKO.
