-
Do not connect to any circuitry
A5
GPI 26
Input
Pull-Down (60 k
)
GPI signal bit 26
A6
TRSTN
Input
Pull-Up (70 k
)
JTAG reset. This pin must be tied to ground if the JTAG
function is not used.
A7
TDO
Output
-
JTAG data output
A8
TCK
Input
Pull-Up (70 k
)
JTAG clock
A9
EPR_SC
I/O
Pull-Up (70 k
)
4 mA
EEPROM serial clock. This pin is used to send serial
clock to EEPROM having I
C interface to download
firmware from EEPROM. For details, see Firmware must
be downloaded into the SiI 3726 SATA Port Multiplier
from a Serial EEPROM for normal operation. The serial
EEPROM is connected to pin numbers A9 (Serial Clock)
and B9 (Serial Data).
Auto-Initialization from the EEPROM on page 20.
A10
RST_N
Input-
Schmitt
Trigger
-
System Reset. This pin is used to reset SiI 3726
A11
EM_ID0
Input
Pull-Down (60 k
)
Enclosure management ID input bit 0. This pin is used to
set the identification number together with other EM_ID
pins for SEMB. For details, see Storage Enclosure
Support on page 11.
A12
EM_SC
I/O
Pull-Up (70 k
)
4 mA
Enclosure management serial clock. This pin is used to
send/receive serial clock to/from Enclosure processor,
and complies with I
C Bus Specification. For details, see
Storage Enclosure Support on page 11.
