POWER MANAGEMENT DATA REGISTER – OFFSET E0h
Bit
Function
Type
Description
Indicates the current power state of PI7C8150B. If an
unimplemented power state is written to this register, PI7C8150B
completes the write transaction, ignores the write data, and does not
change the value of the field. Writing a value of D0 when the
previous state was D3 cause a chip reset without asserting
S_RESET_L
00: D0 state
01: not implemented
10: not implemented
11: D3 state
Reset to 0
Read as 0
Read as 0 as PI7C8150B does not support the PME# pin.
Read as 0 as the data register is not implemented.
Read as 0 as the data register is not implemented.
Read as 0 as the PME# pin is not implemented.
