5.2

Single wire interface module (SWIM) and debug module (DM)

5.2.1

SWIM

The single wire interface module, SWIM, together with an integrated debug module, permits

non-intrusive, real-time in-circuit debugging and fast memory programming. The interface

can be activated in all device operation modes and can be connected to a running device

(hot plugging).The maximum data transmission speed is 145 bytes/ms.

5.2.2

Debug module

The non-intrusive debugging module features a performance close to a full-flavored

emulator. Besides memory and peripheral operation, CPU operation can also be monitored

in real-time by means of shadow registers.

●

R/W of RAM and peripheral registers in real-time

●

R/W for all resources when the application is stopped

●

Breakpoints on all program-memory instructions (software breakpoints), except the

interrupt vector table

●

Two advanced breakpoints and 23 predefined breakpoint configurations

5.3

Interrupt controller

●

Nested interrupts with three software priority levels

●

21 interrupt vectors with hardware priority

●

Five vectors for external interrupts (up to 34 depending on the package)

●

Trap and reset interrupts

5.4

Flash program and data EEPROM

●

8 Kbytes to 32 Kbytes of medium density single voltage program Flash memory

●

Up to 1 Kbytes true (not emulated) data EEPROM

●

Read while write: writing in the data memory is possible while executing code in the

Flash program memory

The whole Flash program memory and data EEPROM are factory programmed with 0x00.

5.4.1

Architecture

●

The memory is organized in blocks of 128 bytes each

●

Read granularity: 1 word = 4 bytes

●

Write/erase granularity: 1 word (4 bytes) or 1 block (128 bytes) in parallel

●

Writing, erasing, word and block management is handled automatically by the memory

interface.
