16-Mbyte off-chip address space for code and data
External bus interface with dynamic bus sizing for 8-bit and 16-bit data ports
Interrupt- or software-triggered
4 CPU interrupts:
32 internal interrupts:
11 external interrupts:
IDLE (HALT, DOZE), SLEEP, STOP
Clock for low-power operation: Low-speed clock (32.768 kHz)
RTC clock: Low-speed clock (32.768 kHz)
On-chip PLL (x4)
Clock gear: Divides the operating speed of the CPU by 1/2, 1/4 or 1/8
Byte 0 is the lowest-order byte (bits 7-0).
The address of a word data item is the address of its lowest-order byte (byte 0).
