Power-Down Operation
2.22 Power-Down Operation
The C6412 device can be powered down in three ways:
• Power-down due to pin configuration
• Power-down due to software configuration − relates to the default state of the peripheral configuration bits
in the PERCFG register.
• Power-down during run-time via software configuration
On the C6412 device, the HPI, PCI, and EMAC and MDIO peripherals are controlled (selected) at the pin level
during chip reset (e.g., PCI_EN, HD5, and MAC_EN pins).
The McBSP0, McBSP1, and I2C0 peripheral functions are selected via the peripheral configuration
(PERCFG) register bits.
For more detailed information on the peripheral configuration pins and the PERCFG register bits, see the
Device Configurations section of this document.
