The PRB Control Field
The Control Field (offset 0x00, bits [15:0]) is used to indicate the type of PRB and features that are desired. For a standard
ATA command, this field will normally contain a default value of 0x0000. Table 5-3 describes the bit functions for each bit in
the Control Field.
Bit
Name
Description
0
control_protocol_override
The Protocol Override Field is to be used instead of the
default protocol for this command.
1
control_retransmit
Allows retransmission if an error occurs during an external
command transmission.
2
control_external_command
The command FIS shall be fetched from host memory.
This feature is used to send arbitrary FISes that will not fit
in the command FIS area of the PRB.
3
control_receive
Reserves a command slot to be used to receive an
interlocked FIS as described by the port FIS_CONFIG
register.
4
control_packet_read
Indicates that the packet command associated with this
PRB will transfer data from the device to the host. This bit
must be set for all packet commands that perform read
data transfers.
5
control_packet_write
Indicates that the packet command associated with this
PRB will transfer data from the host to the device. This bit
must be set for all packet commands that perform write
data transfers.
6
control_interrupt_mask
Setting this bit to one will prevent the SiI3531A from issuing
a normal successful completion interrupt for this command.
7
control_soft_reset
Causes the SiI3531A to issue a soft reset FIS sequence to
the device.
15:8
reserved
Must be zero
