SNotification, shown in
have sent the host a set device bits FIS with the notification bit. When the host receives a set device bits
FIS with the notification bit set to 1, the host should set the bit in SNotification corresponding to the value
of the PM port field in the received FIS. For example, if the PM port field is set to 7 then the host should
clear bit 7 by writing a 1 to it. Next, the host should generate an interrupt if the I bit of the set device bits
FIS is set to 1 and interrupts are enabled.
In this register, bits previously set are explicitly cleared by a write operation or by a power-on-reset
operation. If the register is not cleared due to a COMRESET, the software is responsible for clearing the
register as appropriate.
