ZEUS Technical Manual Power and power management CompactFlash power management The power supply to the CompactFlash interface is controlled via software, and supports hot swap card insertion and CompactFlash power down states. GPIO97 on the PXA270 (signal CF_PWEN) is used to control the power supply switch. Setting this line to logic ‘0’ switches off the power to the CompactFlash interface. The currentlimiting (1A) and thermal protection features of the power switch eliminate the need for the fuse.

ZEUS Technical Manual Power and power management Ethernet power management The Ethernet controllers (Davicom DM9000A) incorporate a number of features to maintain the lowest power consumption. The device can be put into a power-reduced mode by setting the PHY control register bit 16.4. In power-reduced mode, the device transmits the fast link pulses with minimum power consumption.
PAGE 72
ZEUS Technical Manual Power and power management CAN bus power management The Microchip MCP2515 CAN bus controller has an internal sleep mode that is used to minimize the current consumption of the device. The SPI interface remains active for reading even when the MCP2515 is in sleep mode, allowing access to all registers. To enter sleep mode, the mode request bits are set in the CANCTRL register (REQOP<2:0>).

ZEUS Technical Manual Power and power management COM Ports power management RS232 transceivers can be placed in low power mode in case they are not used. This can reduce the power consumption of each RS232 transceiver down to 33 μW. GPIO pins 3 and 4 of Expander 2 (I2C address 0x22) are used to shut down COM1 and COM2. GPIO pin 1 of Expander 1 (I2C address 0x21) is used to shut down COM3.
