from the application software. As long as JTAG is disabled the I/O pins required for JTAG can be
used as normal I/O pins.
Some features in the device is regarded to be critical for safety in some applications. Due to this,
it is possible to lock the IO register related to the Event System and the Advanced Waveform
Extensions. As long as the lock is enabled, all related IO registers are locked and they can not
be written from the application software. The lock registers themselves are protected by the
Configuration Change Protection mechanism, for details refer to
tion” on page
The ADDR2, ADDR1 and ADDR0 registers represents the 24-bit value ADDR.
• Bit 7:0 - ADDR[23:16]: NVM Address Register Byte 2
This register gives the address extended byte when accessing application and boot section.
• Bit 7:0 - ADDR[15:8]: NVM Address Register Byte 1
This register gives the address high byte when accessing either of the memory locations.
• Bit 7:0 - ADDR[7:0]: NVM Address Register Byte 0
This register gives the address low byte when accessing either of the memory locations.
