DM6588A can not assert PME# from D0. But can
Assert PME# from D3(hot) and D3(cold). Hence the
Ring to PME# circuit must check the power state. If
ring comes at D0 power state, it can not assert PME#.
Software will enable its use by setting the PME_En bit
in the PMCSR.
It must continue to assert PME# until software either
clears the PME_En bit or clears the PME_Status bit.
Before enter D3(cold) state, host must :
1. Write 1 into PME_Status bit to clear previous
PME status
2. Write 1 into PME_En bit to enable PME
function.
3. Write 3 into Power_state
4. Power off PCI bus.
When Ring comes, Ring to PME# circuit check if
PME_EN=1 and Power_staus <>0. If yes, assert
PME# and set PME_Status=1.
When host detect PME# asserted, it will power up PCI
bus and assert RST# to initialize pci modem. At the
same time, it write 1 into PME_En bit or PME_Status
bit to stop PME#.
Before enter D3(hot) state, host must :
5. Write 1 into PME_Status bit to clear previous
PME status
6. Write 1 into PME_En bit to enable PME
function.
7. Write 3 into Power_state
When Ring come, Ring to PME# circuit check if
PME_EN=1 and Power_staus <>0. If yes, assert
PME# and set PME_Status=1.
When host detect PME# asserted, it will re-initialize
pci modem and set Power_State=0 to return D0 state.
At the same time, it write 1 into PME_En bit or
PME_Status bit to stop PME#.
