CONFIGURATION
0
RAID Class, PCI Class Code = 010400h
1
IDE Class, PCI Class Code = 010185h
Table 3-2: ATA Configuration
This pin has an internal pull-up resistor, and if left unconnected, will default to ‘1’. Otherwise, tie this pin high (1,) or low (0)
to select the desired mode.
It is recommended that this pin to be tied to low (RAID Class) when Silicon Image drivers (RAID or Non-RAID) are used.
Base Address 5 Enable
Pin Name: BA5_EN
Pin Number: 139
Base Address 5 Enable Jumper Pin.
BA5_EN Pin

Base Address 5 Enabled
Table 3-3: Base Address 5 Configuration
Note 1: Reading Base Address 5 returns all zeroes.
This pin does not have an internal resistor and therefore must be tied high (1) or low (0) to select the desired mode.
It is recommended that this pin is enabled (tied high)() for all configurations.
Internal Scan Enable
Pin Name: SCAN_EN
Pin Number: 142
This pin when active (high) will place all scan flip-flops into a scan mode. This pin should be tied to ground for normal
operation.
Memory Chip Select
Pin Name: MEM_CS_N
Pin Number: 143
This pin is used to select and enable the external memory. It is active low.
