The CPU uses a Harvard architecture, so that memory is organised in two separated fields:
program memory and data memory. As both memory are separated, the central processing
unit can read/write data at the same time it loads an instruction. Peripherals and system control
registers are mapped on data memory space.
Program memory is fitted onto one page. Data is made of several 256 bytes pages.
The program memory is implemented as Multiple Time Programmable (MTP) Flash memory.
The power consumption of MTP memory is linear with the access frequency (no significant
static current).
Size of the MTP Flash memory is 8192 x 22 bits (= 22 kBytes)
Size of the ROM memory is 6144 x 22 bits (= 17 kBytes)
