User manual
The System Control Block includes several system features and control registers for a
number of functions that are not related to specific peripheral devices. These include:
Each type of function has its own register(s) if any are required and unneeded bits are
defined as reserved in order to allow future expansion. Unrelated functions never share
the same register addresses
Table 3–22
Table 22.
All registers, regardless of size, are on word address boundaries. Details of the registers
appear in the description of each function.

Pin description
External Interrupt Input 0 - An active low/high level or
falling/rising edge general purpose interrupt input. This pin may be
used to wake up the processor from Idle or Power-down modes.
External Interrupt Input 1 - See the EINT0 description above.
External Interrupt Input 2 - See the EINT0 description above.
External Interrupt Input 3 - See the EINT0 description above.
External Reset input - A LOW on this pin resets the chip, causing
I/O ports and peripherals to take on their default states, and the
processor to begin execution at address 0x0000 0000.
