Specifications

(1)

The Flash module is not powered down by hardware in any LPM. It may be powered down using software if required by the application.

For more information, see the Flash and OTP Memory section of the System Control chapter in the TMS320F28004x Microcontrollers

Technical Reference Manual.

(2)

The XTAL is not powered down by hardware in any LPM. It may be powered down by software setting the XTALCR.OSCOFF bit to 1.

This can be done at any time during the application if the XTAL is not required.

5.9.8

Low-Power Modes

This device has HALT and IDLE as two clock-gating low-power modes. STANDBY mode is not supported

on this device. See the TMS320F28004x MCUs Silicon Errata for more details.

Further details, as well as the entry and exit procedure, for all of the low-power modes can be found in the

Low Power Modes section of the TMS320F28004x Microcontrollers Technical Reference Manual.

5.9.8.1

Clock-Gating Low-Power Modes

IDLE and HALT modes on this device are similar to those on other C28x devices. Table 5-33 describes

the effect on the system when any of the clock-gating low-power modes are entered.
