Advisory

LPM: STANDBY Low-Power Mode is Not Supported

Revisions Affected

0, A, B

Details

The STANDBY low-power mode is not supported.

Workaround

The IDLE or HALT low-power modes can be used for power reduction. See the TMS320F28004x Real-Time Microcontrollers Technical Reference Manual for information on implementing these modes.

If IDLE is used, additional power reduction can be optionally achieved through software by one or all of these methods:

  • Decrease the SYSCLK frequency:
    • Change the SYSCLK source to OSCCLK by configuring SYSPLLCTL1[PLLCLKEN] = 0.
    • Change the SYSCLKDIVSEL register to a higher divider.
  • Disable peripheral clocks through the PCLKCRx register.
