6.2 Power Management
The LAN100 supports power management by means of external clock switching.
Basically, all clocks in the LAN100 module can be switched off. If WoL is needed, the
receive clock should not be switched off.
The LAN100 supports two power management modes:
The LAN100 can be put in sleep mode by setting the PowerDown bit in the
PowerDown register if the receive and transmit DMA managers are disabled and
inactive. Clocks should only be disabled after software has set the PowerDown bit.
Software should prevent access to components of the LAN100 that have been
switched off. If an external PHY is connected, a WoL can still trigger an interrupt.
To enter sleep mode, software should:
If no PHY is connected software can directly set the PowerDown bit and disable the
clocks.
To exit sleep mode sofware should:
In coma mode, most of the clocks in the PNX15xx Series can be switched off
including the CPU and MMIO clocks. If an external PHY is connected, the receive
filter and WoL detection will still be active and capable of generating a WoL interrupt
to the system’s power-management controller.

Sleep mode : the PNX15xx Series is active while most clocks are switched off.
The CPU is active and can still communicate with the LAN100 via MMIO
registers.
Coma mode : most of the clocks in the PNX15xx Series are switched off, including
the LAN100, CPU, and MMIO clock.
Disable both transmit DMA managers and the receive DMA manager by writing
the Command register
Wait for the transmit and Receive Datapaths to be inactive by waiting for a
Finished interrupt or by polling the Status register.
Set the PowerDown bit by writing to the PowerDown register.
Reset the PowerDown bit
Reenable the receive and Transmit Datapaths.
