Detailed Description

(1)

IEEE Standard 1149.1-1990 Standard Test Access Port and Boundary Scan Architecture

6.1.5

Peripheral Bus

To enable migration of peripherals between various Texas Instruments (TI) MCU family of devices, the

devices adopt a peripheral bus standard for peripheral interconnect. The peripheral bus bridge multiplexes

the various busses that make up the processor Memory Bus into a single bus consisting of 16 address

lines and 16 or 32 data lines and associated control signals. Three versions of the peripheral bus are

supported. One version supports only 16-bit accesses (called peripheral frame 2). Another version

supports both 16- and 32-bit accesses (called peripheral frame 1).

6.1.6

Real-Time JTAG and Analysis

The devices implement the standard IEEE 1149.1 JTAG (1) interface for in-circuit based debug.

Additionally, the devices support real-time mode of operation allowing modification of the contents of

memory, peripheral, and register locations while the processor is running and executing code and

servicing interrupts. The user can also single step through non-time-critical code while enabling time-

critical interrupts to be serviced without interference. The device implements the real-time mode in

hardware within the CPU. This is a feature unique to the 28x family of devices, requiring no software

monitor. Additionally, special analysis hardware is provided that allows setting of hardware breakpoint or

data/address watch-points and generating various user-selectable break events when a match occurs.

6.1.7

Flash

The F28069, F28068, F28067, and F28066 devices contain 128K × 16 of embedded flash memory,

segregated into eight 16K × 16 sectors. The F28065, F28064, F28063, and F28062 devices contain 64K ×

16 of embedded flash memory, segregated into eight 8K × 16 sectors. All devices also contain a single

1K × 16 of OTP memory at address range 0x3D 7800 – 0x3D 7BF9. The user can individually erase,

program, and validate a flash sector while leaving other sectors untouched. However, it is not possible to

use one sector of the flash or the OTP to execute flash algorithms that erase or program other sectors.

Special memory pipelining is provided to enable the flash module to achieve higher performance. The

flash/OTP is mapped to both program and data space; therefore, it can be used to execute code or store

data information. Addresses 0x3F 7FF0 – 0x3F 7FF5 are reserved for data variables and should not

contain program code.

NOTE

The Flash and OTP wait-states can be configured by the application. This allows applications

running at slower frequencies to configure the flash to use fewer wait-states.

Flash effective performance can be improved by enabling the flash pipeline mode in the

Flash options register. With this mode enabled, effective performance of linear code

execution will be much faster than the raw performance indicated by the wait-state

configuration alone. The exact performance gain when using the Flash pipeline mode is

application-dependent.

For more information on the Flash options, Flash wait-state, and OTP wait-state registers,

see the Systems Control and Interrupts chapter of the TMS320x2806x Piccolo Technical

Reference Manual (SPRUH18).
