9.3.1 CPU Memory Map and Interrupts

When the device comes out of power-on-reset, the data memories are mapped to the processor as follows:

Table 9-1 Memory Map (After Reset Operation)
Address Size Module
0x0000_0000 – 0x0000_FFFF
In 16 repeated blocks of 4K each		 16 X 4K Boot ROM
0x0001_0000 – 0x0001_7FFF 32K Program flash
0x0001_8800 – 0x0001_8FFF 2K Data flash
0x0001_9000 – 0x0001_9FFF 4K Data RAM

Just before the boot ROM program gives control to FLASH program, the ROM configures the memory as follows:

Address Size Module
0x0000_0000 – 0x0000_7FFF 32K Program flash
0x0001_0000 – 0x0001_AFFF 4K Boot ROM
